Life happens everywhere . It adapts to different situations. How arrogant is that of people to think that we're alone in the universe ? The most extreme places on earth have life . Whether its hot or cold . I bet there's more life than we know about in the ocean . We having even searched the whole ocean .
We see it on Earth that most places on this planet have life, in the deep dark oxygen-deprived ocean trenches to hot acidic springs in the Yellowstone Park to the driest desert. There could be life on Mars that either originated there or here by hitchhiking on space rocks. We might even be Martians ourselves. And Jupiter's moon Europa could have life that originated independently underneath the ice shell where there is strong evidence of a liquid water ocean. And lastly we are beginning to find planets around other stars that have similarities to Earth and they could have oceans atmospheres and probably life.
The universe is far too vast for there not to be other instances of life, outside of Earth. We may never know, but there are universes upon universes, and we are just a little speck in our universe. There is just no way that we could be the only carbon-based accident in the universe.
Conditions for some kind of life are most likely to exist somewhere in the Universe. We may never meet it or we may never be able to recognize it, but the likelihood of us being the only ones is both arrogant and unscientific.
The number of new "planets" being discovered every day means that the chances of the conditions for life being duplicated are very very high.
It only makes sense that there is some other planet or galaxy that has life on it. I mean, think about it, if earth is the only planet in the whole universe that has life, then most of the universe would practically be dead, not living, inanimate, whatever you might say. God may have created earth, but to keep the universe alive, he must have created other planets and galaxies with life, too.
Some bacterias and virus came from space. Like the ebola virus and other viruses. Life doesn't pertain to human-like beings alone. But it also pertains to every other species living outside out planet. I also support that there are extraterrestrials living in other galaxies, perhaps not in our solar system but there's millions of galaxies beside ours. So there's a large possibility of life existing in other planets.
Life as we know it survives heavily on water and oxygen, and the search for life outside of earth has primarily been focused on finding these substances. However, our understanding of life is based on one example, earth. Therefore I think that life outside earth may well not need water or oxygen. They may have alternative substance for survival. Given the huge amount of chemicals that may be formed from the elements, it could well be the life outside earth survives on these other chemicals as opposed to the chemicals we see as vital to life, on earth.
Yes, I totally agree that the life do exists outside of the earth. The very fact that many developed nations are spending lots of money to find out whether the life exists outside the earth is the evidence of existence of life. Moreover, there were evidence found in the soil of planet Mars which was sustainable for the existence of human being, so I agree there exists a life outside of the earth.
We are told that the universe is unending, infinite. It seems egotistical and irrational to imagine that earth is the only place, out of a space that goes on for eternity, where there is life. There has to be life of some kind besides just us earthlings out there. It might be something entirely different than we could ever imagine, but I believe there has to be some type of life form besides us.
I think that it is possible for life to exist outside of earth, whether in other universes or other dimensions, if only on the basis that there is no way to say for certain that there is not. I think that what we see from our perspective is very limited, and that it is (typically) arrogant to assume that our planet is the only "living" planet. I also question our definition of life -- as everything is composed of the same particles on the atomic level, who is to say that our definition of life is even correct?
As astronomers discover other solar systems in our galaxy, this should help the argument that life can possibly exist elsewhere in the universe. If each galaxy is full of solar systems, then conditions should be right for life on some of these planets. Our galaxy is just one of who knows how many, making for an almost infinite number of possible places where life could occur. It certainly may not be the same as here, but life nonetheless.
I have read lots of others words. I agree there has to be other life out there. I believe this because there is still so much space out there that we haven't discovered and that we may never know. All though other planets may not have similar environments such as ours life may be living off of other substances. Also it may be possible that other planets have life and environments similar to ours but because we might not have the technology to see this we may never know because there's to much space... Also i found it is true that because of our technology it takes us long amounts of time to even get to other planets, even if we get to traveling at the speed of light by the time we get to other planets they maybe gone.
The universe is vast i think there is a lot of things still unknown to humans. Something out there is staying hidden so far. There is some thing which may be more powerfull or may more weaker than us are hiding in the universe. I fell sure there is something out there.
Of course there is, of course, we might never see any signs of it either. Someone here was saying that there isn't any because they haven't contacted us or made themselves known in any other way, so no intelligent form of life can exist because they haven't told us they are here, well we are a form of intelligent life and we haven't let anyone else know we are here so go figure. There are galaxies that have over 100 billion stars in them, now add that to the billions galaxies out there and try and tell me that not one, one single one of them is harbouring life, because I for one(and many others) believe you are just ignorant to believe that there isn't.
Well one thing is we can't be the only planet in this universe, it just makes me feel lonely. There could be a planet, out there somewhere in our universe or even maybe outside that is also looking for another planet. There could be another galaxy out there similar to us, the sunlight, water and land one a planet. If we are the only life in this dimension, in this universe, in this life, then what's the point of being here. Life could form on another planet just like how we evolved from the beginning of earth. Amazing that we got this far only on a limited resource planet but soon it will be mandatory to find another planet like ours due to some consumers who abuse some of our resources. We know that space is the final frontier and we can continue the human race.
We should know that this isn't the only living planet.
And there are likely billions more that we haven't even discovered yet. You need to consider light and it's speed here. Light takes a long time to travel, so a Habitable planet about 100LY away would see what was happening on Earth about one hundred years ago, and vice versa if we could observe them. Now consider there's habitable, or in this case once habitable planets thousands, even millions of Light Years away. If we were to observe them now, we could see them. But they may have already been extinct millions of years earlier. Now the same said goes for uninhabitable worlds of the same distance. They may not have life to our sight if we could observe, but if we were to travel there faster than the speed of light, it's highly possible that life may have already evolved and we just didn't know it. What I'm saying is, although we may never see life outside of our own Planet, there's an almost absolute chance that it does exist.
To argue that life only exists on Earth flies in the face of probability. The question is not if we will ever discover E.T., but if E.T. might exist. If there was just one other planet with life, that could be so far away that we could never discover them (even we could travel at light speed) then the answer to this question has to be YES.
People have been visiting other places in our solar system for the past 50 years. But, aside from Mars and the moon, we have not ventured far enough out to prove there is life on other planets. It would be ignorant to think we are the only planet, out of the 9 planets, to have life.
The Bible is the only supporting evidence, in the spiritual sense, of heaven and hell. I do believe this is a physical place, with souls or beings living there. This evidence comes by way of faith through the Bible. There being other beings on planets is also a belief that I have, because the universe is so big. But, this is also a faith-based evidence to me. So, I am sure of heaven and hell, but not totally convinced of beings on other planets. But, it is possible.
There are two possible standpoints from which one can view the possibility of "other" life in the universe. One is religious and one is scientific--although this oversimplifies this discussion.
What if one believes that God/Goddess/Spirits created this world and everything in it, in keeping with most religious writings. Does that mean that there can not be life anywhere BUT on this particular planet? If it does mean that we are all there is--is that not assuming limitations on God's powers, abilities and imagination? If God did indeed create this world in seven days, that leaves 51 weeks in that one year for Him/Her/It to be out there creating all sorts of other worlds and creatures and environments. Is it possible even, that we were a rough draft, and that God did his best work somewhere in the Andromeda Nebula?
Now for the scientists among you. You might say that the particular convergence of that "primordial soup" from whence we came with the perfect planetary conditions for it to cook to perfection just could not happen again. It was too random. Too haphazard. Nonsense. Just because an event is random does not mean it is unique. There ARE others out there.
We can't survive under water without supplemental oxygen, but there are creatures that can. So maybe there are creatures out there that can live on nitrogen, or that have the ability to live in high temperatures. Just because we can't doesn't mean something else can't; we don't know everything.
When you dip a glass of water into the shallow area of the ocean do you necessarily have to have fish in it when you take it back out ? No, and if there is no fish in your glass of water is it safe to assume that all of the ocean is empty of lifeforms? No.
Space is similar, scientist have only dipped their toes In the "water" ; there are millions of galaxies; thousands of terrestrial planets and similar solar systems. For those whom are religious, if god created us with love why must we be jelous, god created dogs, cats, lions and all of his creations with the same love he created us with. Let's not be blinded by "jelous god belief" believe me god is the last being you wanna call jelous!
The size and scale of the universe by itself is enough to predict that we are not alone - that sure would be a gigantic waste of space. The reason we have had no encounters is simply because of this scale - it would take 4 years traveling at the speed of light to reach the next nearest star.
Foremost, using statistics and probability, you can use infinitesimal odds that life might exist. For example, in the journal of Astrobiology, Professor Andrew Watson gives a 0.01 percent chance that life might emerge over the four billion year history of our universe. Yet, even with those numbers, we have found in the last 20 years that biological life did occur on Mars; a planet within our own solar system. Clearly, that shows us easily life can occur, exist, and thrive on other planets, even under difficult odds.
In this day we shouldn't stay naive because we're afraid to let go of the Bible. I think we as people, being far more intelligent have realized how very small we are in a very big universe. The bible provides us with nothing other than comfort, it is simply not true.
There's water on other planets and also why would there be so many solar systems and galaxies if they were all uninhabited? There's also the black night satellite that is old and artificial, scientists don't know where it came from or when it came into orbit. So that is why I do believe that there are other living organisms out there somewhere, somewhere maybe they've found us and we just need to find them.
If you look at what we are made up of, you'll find that 65-70% of our body is made up of water. Water = Hydrogen and oxygen. Carbon (18%), Hydrogen (10%), Nitrogen (3%), Calcium (1.5%), Phosphorus (1.0%), Potassium (0.35%), Sulfur (0.25%), Sodium (0.15%), Magnesium (0.05%), Copper, Zinc, Selenium, Molybdenum, Fluorine, Chlorine, Iodine, Manganese, Cobalt, Iron (0.70%), Lithium, Strontium, Aluminum, Silicon, Lead, Vanadium, Arsenic, Bromine (trace amounts).
Where did all these come from?????!! They certainly did not just pop up out of nowhere and decided to make life on a lump of rock and metal. These elements were created from the core of stars. Helium and Hydrogen, also forming the heavier elements as it cools down eventually forming everything from oxygen to iron. When these stars "die" or explode, they scatter these elements across the universe, some to form new stars, others to land on a lifeless rock to create what we are today. This is happening all over the universe all the time. We don't find helium in our bodies because we have no use for it, but some where, in the vastness of space, there exists life that might actually have use for helium and not oxygen. There is no doubt that their is life beyond or planet, we just haven't found it yet, humans could only look so far, but one day, if we don't kill ourselves in this crazy world, we will live long enough to find what we are looking for.
"Life doesn't exist anywhere but earth? That's like taking a cup of ocean water and saying there aren't any whales in the ocean." - Neil deGrasse Tyson.
The probability that the universe is 50 times greater (larger) than what we currently know is very very likely.. It would seem unlikely that there are no other planets throughout this great universe that is not at least the age of the earth..Furthermore, we can only measure how life may have occurred on earth but we still do not have 100 percent assurance of how it came about on this planet..Also even if it would take a billion years for an intelligent life to come about (and that is solely going off of what WE as human know how life MAY have come about!) The unknown age and complexity of the universe would still be a big factor in determining the existence of complex intelligent life.. The average scientist will clearly tell you that the possibility of life existing on other planets is very small and not likely, and that is because the planetary bodies in our solar system are so far spread apart that is would indeed seem impossible for any such exploration to even closest planet that May Harbor life.. And also the fact that none of the planets that surround us seem have any life, not even basic single cell organisms.. So yes, it would appear that we are alone in the universe..
But what I do know is we as human cannot comprehend many occurrences and phenomenon on our own planet yet alone other planets...
I haven't got a chance to read all the answers above so never mind if my views get similar to those of others.
Galaxies on average contain at least a billion stars. Our sun is just an ordinary medium sized star that has a bunch of planets moving around it. So not hard to imagine that a lot of stars might have their planets moving around them too. Add on that there are countless galaxies out there in the infinitely growing universe. So for anybody who gets the feel of universe's vastness and infinite solar systems, it is just impossible to believe that life doesn't exist anywhere else but only on Earth.
Life might exist at a lot of places, it is just a matter of time before we can finally be able to discover it. Maybe other advanced civilizations have already discovered us and if not, they might be desperate to discover us too.
Newton's law is every action has a reaction. Therefore every action created in our planet has a reaction anywhere in the universe. When there is a creation, a destruction also exists. An opinion is god created man wheras there is a reverse man created god. So this planet will also be destructed as once it created and again & again creation & destruction will come in a cyclic order.

Collect all the sand in the world and put in one big pile, it would probably reach out into space, then take eyebrow tweezers and carefully take one grain of that sand from those trillions and trillions of tons of sand, then somehow cut that one tiny grain of sand into eight pieces, one of those eight bits would represent the Earth. And you still think there's no life on other planets.....I think not.
Think about it, we are a tiny little pin in this vast enormous universe. It would be almost IMPOSSIBLE for there not to be another planet, or moon, or..... Star?? With life on it, even if it's just ONE celestial body, even if they are just unicellular entities there has to be more of us somewhere. Forget the distance. The universe is 14 billion years old, if we could develop in this time, so could have other things PLUS our solar system is very new. This means that there could be life out there even more developed than us, who knows, maybe tomorrow we will get a knock on earth's door with other beings paying us a visit. Whether it be for good reasons, or for bad reasons. I believe in the time I'm alive, I will see an extraterrestrial entity with my own eyes. Scientists have been getting radio signals too normal for pulsars or any other celestial body we know of, this could be an alien sending us signals.
The universe is huge and amazing. I truly believe we are not alone. There must be some possibility that life may exist outside Earth. Even Mars has some proof that life could have existed there. But hey if some people can believe there is a celestial being "God" then why can't life outside of earth exist?
We don't know if earth is, so I think yes. And we have no clue unless you go out of earth and prove it to us. For now, I say yes. But, people say no we have no facts. I hate when people say when they know the Earth but they really don't. If you have proof, show the world!
Why did I say that there is a life outside the earth? Outer space is composed of millions of galaxies which contain billions of planets. What if one of them is an earth-like planet? There is no impossibility in outer space, since space is full of mystery. Maybe one of the planets in the solar system is a home for aliens.
Yes, because I think the same processes we see here on earth happen everywhere in the universe. Since we are a part of the universe, I can't think we are an anomaly. I can only conclude we are just a reflection of what we see in the sky at night. We are part of the night sky too. Who knows, someone far away might be checking us out. I'm annoyed when folks try to measure distance using light speed. I lose interest when people talk about UFOs. Einstein, as imperfect as he was, proved with a little help that light bends around large objects in space. This was proved by an experiment decades ago when an eclipse of the sun was measured. The same experiment has been repeated by NASA scientists scores of times with the same results. One would think that people would realize that using light speed to measure travel between celestial objects is out of date. If we are being visited by our cousins I think they probably have some knowledge about how to get from point A to point B without x number or light years as part of their equation. Maybe space bends or can be folded.
If there was a planet without life then what was it created for? it's just like us, we were once nothing when Earth first created, We evolve, like dinosaurs and such. Other planets might have different temperature, weather, and different lifeforms, but I think it's the same concept as how we were created through evolution.
I believe that life exists outside of Earth. It is ignorant to believe that Earth is the only planet in the universe to have the ability to sustain life. Also, to think that all life must be supported by our own necessities is asinine. The universe is boundless, the possibilities are infinite.
The universe is incomprehensible to the human mind. Where we see limits the universe sees infinite potential. We cannot be alone and it would be ignorant to assume so. While we may have not found life yet, we will find life on other planets this century. Life has been able to exist on the most harshest environments on earth, we will see the same across the void of space.
newton's law is every action has a reaction. therefore every action created in our planet has a reaction anywhere in the universe. when there is a creation, a destruction also exists. an opinion is god created man wheras there is a reverse man created god. so this planet will also be destructed as once it created and again & again creation & destruction will come in a cyclic order.
Humans have always considered life to be based around the concept of water and oxygen. It is extremely possible that life can exist without such elements. There are currently bacteria that only need methagen to survive. There are extreme halophiles, and those that thrive in the hottest conditions, called theromophiles. If humans would expand on this concept, then it would be relatively easy to grasp the idea of other living things, outside the realms of earth.
Because there could be a other planet that we don't know about an the science could find out if there is a other planet were people will live in even titan maybe can be a planet were can people live in how thinks there is a another planet were people can lived in
People who think that life does not exist in the universe, I do not understand them, imagine how giant the universe is there might be infinite places that life exists, maybe even an exact copy of our world.
There is a theory that the universe is infinite how can there possibly not be a other planet that has life on it.
I am pretty much positive that there has been life outside of Earth in the past, there is life outside of Earth right now, or that there will be life outside of Earth at some point. There's all this talk about Mars having water in the past, but there are other planets that we know of that currently have water on them. There's Europa (actually one of Jupiter's moons) which has lakes underneath its surface and a huge ocean which is 100 kilometers deep (62 miles)! Scientists think that the ocean's warmed by lots black smokers, like on Earth. These are life-supporting environments and may contain creatures. GJ1214b is one of the 730 extrasolar planets we've been able to detect and it's called "The Water World." It's covered with an ocean thousands of kilometers deep. There could probably be life lurking on this planet and others like it as well. There are some pretty Earth-like extrasolar planets too like Kepler 22-b and Gliese 667 Cb. And there is so much more for us to explore. Space is just so vast. With discoveries like the ones mentioned we'll definitely come across more and hopefully be able to observe them enough to discover the creatures that could be living on them someday.
If they haven't given us a sign or we haven't seen enough, remember they could think same about us, we haven't given signs... Also we haven't reached far, actually we just have reached a bit, more likely less. Life out there might be inferior or superior to us. Don't get me wrong, I see there is no evidence of life out there but we humans are smart enough to at least believe a bit in it.
My argument for people who believe in God like me, the Bible doesn't say or deny life from other planets! And I think the universe is big enoug or too big for life in other planets to exist. We are a planet from a solar system from a galaxy with life. Now think of this, there are many other galaxies, I don't think they're empty.
For atheists, same thing, the universe is vast, enough to hold way more than one living organisms. We just know about our galaxy, our solar system and some planets but there are lots of unknown areas in space we don't know of that could sustain life!
If our entire universe was like sand in a beach, there would be millions of grains of sand. Each grain is one galaxy. Many of the galaxies are far beyond our reach. We cannot say that life does not exist outside earth. There may be planets in other galaxies which may have everything needed to support life, though we may not know it.
Majority of planets are far away from earth where we can't reach in entire life and not able to analysis any thing then how we can say that life is not possible on other planet. Note that according to science lots of galaxy in this universe and earth is very little as compare to other planets. Even we are not 100% sure about Mars which is the part of our solar system. When we are not sure about our solar system then how can say about another solar system which are beyond our reach. If our reach is limited then it's not mean that possibility of life outside earth is limited.
Because if humans can imagine something, is because it exists... That's why I'm scared, because there are many movies about the end. Because if humans can imagine something, is because it exists... That's why I'm scared, because there are many movies about the end. Because if humans can imagine something, is because it exists... That's why I'm scared, because there are many movies about the end.
Life exists due to the fact the universe is so big if earth was the only planet to have life in the universe, the universe would be dark and dead without other life it would empty and that would be horrible there might be no prove but there has to be life.
I find it a ridiculous notion to say this is the only planet in the universe with life and I'm religious. Its arrogant to think that life can only exist in a so called "perfect" solar system like ours. No planet or solar system is exactly like ours. I believe first contact is only a matter of time.
In the words of Jodie foster in Contact, "The Universe is a huge place. Its bigger and more beautiful than what anyone in history has ever dreamed of and if its just us, seems like an awful waster of space.''
1. Our increasing knowledge of the universe - it was only a relatively short time ago in cosmic terms that we believed we were the only planet in the universe. A position that now needs absurd.
Important new discoveries are now made on a daily basis showing our complex relationship with the universe. We are not far away from answering this question in a way all parties would accept. If I had to hazard a guess I would say 2073 - a hundred years after the birth of the modern computer. It may well be earlier but this seems a reasonable timetable looking at the rate at which are species has developed so far.
2. The true proof in empirical terms is only going to come when we build space ships fast enough to fly out of our solar system/galaxy and or discover how to navigate a wormhole (if they exist) to travel from galaxy A to galaxy B and physically/psychically meet ET. This seems unlikely in my lifetime. I am 49.
3. I think it unlikely that they would make first contact with us as our solar system is in truth pretty boring when you look at the others on offer from ET's perspective. Not really much to do or see on Earth orthe other planets compared to neighbouring systems. Why would you want to go to Mcdonald's for a dodgy quarterpounder if you had the offer of a free 5 course meal at the Gavroche ?
4. It is existentially depressing to think that all we do is be born eat talk mate marry and die and that's it. Nothing else outside planet earth and no prospect of ever meeting loved ones again when we are finally snuffed out. You have to believe there is a wider picture to make it all worthwhile and preserve your sanity. The only way to navigate this philosophical conundrum is to ignore it (ignorance is bliss position) religion (there is a new happier order after we perish) hope that there is something truly significant beyond the ebb and flow of planet earth. Whilst I row for position 3 the other two positions are so very tempting but in the end they are like the tasty looking fruit that have no taste and give you false promises that never deliver.
If earth can sustain life. Other planets can also sustain life. There are many galaxy and many many planets in our universe so there can not be only one place with life. Although there is no signs of life, water was found on mars and life needs water. And there was also signs of movement on other planets.
Everything that we know of now came from something. I was reading up on Abiogenesis and that makes me believe even more that there is life. Most common elements in life are Hydrogen, Carbon, Oxygen and Nitrogen. I'm sure there's plenty of that out in the universe. There is ET!
I think that Earth is a small planet compared to many many others. We have no idea how many planets there actually are. We do not know how big the universe is but it is huge. The chance that Earth is the only place for life is tiny. Plus, Earth has existed for a long time and life has developed itself. This can always happen on any planet. I even think that not all life has to survive on oxygen. Here are just a couple of quick ideas. I just believe that the is life outside of the Earth, it is hard to believe that there is not.
The universe is enormous. Stupendously enormous. When you imagine how big our universe is, and the abundance of the molecules that make up all life as we know it, it is arrogant to think there is no other life, other than earth-life. To put things into perspective; there are more stars in the universe than there are grains of sand on every beach on our planet. It's utterly arrogant to think we are the only intelligent species that exists.
Although we have not discovered life on different planets, it is very likely that there are extrasolar planets that support life. In fact, there are probably billions of planets with life, and maybe even other life on our nearest star, Alpha Centouri! There is also a chance of life in our own solar system, and Mars, The Moon, other planets moons and even Venus might have life on it! Enough with Humans Bragging about "intelligent" life, us, supposedly, and start considering others, thousands of light years away!
With just how vast the universe is, I would find it harder to believe that Earth is the only planet with conditions that can sustain life. There is little doubt in mind that there are planets out there with life, perhaps even forms of life that are yet unfamiliar to us. It's possible that these planets may even exist within the currently observable universe. We have only physically explored as far as Mars. However, I also think it's very unlikely we'll encounter these "aliens" within our lifetimes.
Infinity goes on endlessly, and our universe is supposedly infinite. That means that there are an infinite amount of planets, suns, stars, etc. So in short, it would be highly unlikely that Earth is the only planet to be able to develop life in a universe of infinite time, space and possibilities.
Out of the hundreds of exo-planets we've found there's one in the "habitable zone" range of it's star. However, we're only a spec in the universe. Our visual field in itself is a spec. No, less then a spec. It is so small we can't even fathom it. Also, our planet, and ourselves, are composed of the same elements as any other mass containing object in this universe as we know it. So who's to say that somewhere one of the millions of stars we can see, or one of the countless amount of stars we can't see, has a planet that supports some life form? It's illogical to think there''s no life outside our own.
It'd be pretty depressing if Earth was the only planet in the entire universe that has life on it, no? For me it's hard to image, us being completely alone in space, nothing else alive but us.
All I read/hear when people are discussing life on other planets is that it's a small chance because there's no oxygen and not a lot of water or resources, and I can't help thinking that maybe other lifeforms don't need the materials we do. Nothing is impossible, I think, so who's to say there can't be other lifeforms in this grand universe?
The universe is vast, with thousands of other galaxies and thousands of other planets. It would be pretty ignorant to think that we are actually alone, that we are the only planet that has life. I mean, there have found fossilized bacteria on Mars, so there is bound to be other planets with life.
There has to be life outside Earth. Earth is in The Milky way Galaxy, only one of millions of other galaxies that we know. Image the one's we don't know of yet. There has to be life somewhere else out there if there is life in our little galaxy. It's not even a question to me anymore, it's just a matter of time when we actually see another race of life outside of Earth Image how incredible that would be! It can't even be put into perspective.
While it is possible we could be the only life in all of the universe, I think it is highly improbable. Just look at ALL the life on Earth and then think...This can't be possible only here. When we as humans think of life we think of living breathing creatures but what if the other life was not. What if they were possible in ways never seen?
The odds of Earth being the only planet with life in such a large universe is slim, there has to be something else than us. Even if we never contact each other, we can't be alone. And if we are alone, what a depressing and sad realization for us all.
I think of all the stars in our observable universe. Already billions in our galaxy. Even with a naked eye can I see more galaxies. Why, among all of these grains of sand, should our Sun and Earth be the only system to harbor life?
Sure, I agree the distribution might be too sparse for us to ever encounter another living world. The lack of technology and limits in communication range might keep ALL of us isolated from each other forever. But I'm here, sitting and wondering, gazing the stars. Considering the Drake equation, quite probably some other being, light-years away from my home, is doing the very same thing.
So next time I sit by the lake and look up into our Universe, I wonder how is it like on the other shore, by another lake in a world far away.
Commom sense. I would hate to be so narrow minded as to think that earth is the only planet revolving round a star that could support life. The only account that it doesnt is from a biblical point of view which is just that, a point of view.
Our galaxy is infinite and to say there is no chance other life resides within is absolutely ridiculous and pretty arrogant. Now, if there is other life out there, they would look like something completely out of reach of our own imaginations. Considering the chances of them having all of the specific conditions on Earth is slim to none. Nonetheless Extraterrestrial life is more than possible, it's almost inevitable.
The Holy Bible is God breathed and not a personal interpretation of man. Now it doesn't say anything other than earth having the creatures created by God. Also the bible states that he created the Sun and the moon. He didn't say that it was a star. There is a clear distinction of god creating the sun and the passage stating that he created the stars also.
I'll probably get slated, insulted and called an idiot.
The Universe is around 14 billion years old, plenty of time for life to develop and expand, evolve into all sorts of weird and exotic forms, gain intellect and use technology, even without developing faster-than-light travel. There has been plenty of time for us to be visited.
There is no evidence of life outside this beautiful world, not even a microbe.
If there is life out there, where is it? An intelligent race would have visited us by now, or we'd at least know of their existence. Never mind the huge, unimaginable distances. But billions of years is plenty of time... where are they?
Simple, there aren't any. I really feel we are truly alone, as depressing as that sounds.
Watch Melancholia, great depressing movie. I just feel we are alone.
There's no reason for life to evolve. Planets, stars, galaxies are organisms of their own.
If there were other advanced life forms out in the universe, I believe they would be here already visiting the earth. We would have trade systems in place, space ports and all sorts of technology and communications established. The distances in space to other worlds would require a very long time of travel to cross the void. Planets with people living on them would need a global cooperation and money to build an enormous ship or "ark". That would require many generations of people being born and dying on the ship to ensure a population to cross the barrier of space. The people would have to remember their mission and keep the ship in operation for thousands of years until they reach their goal and arrive at a planet; say earth. Science fiction gave us romantic notions there are ways to cross the barriers of space which are fanciful delusions. We are grounded by physics and reality.
When one truly understands that complex life requires not just the synchronization of events but entire systems. And this stability must maintain for hundreds of millions of years. The equation illustrating requirements for life is very complex - high degree of chance at each point along the path and any part that = zero renders the whole equation void. More planets does not mean greater chance of life, In the cosmos it just means more chaos, and less chance.
I've always seen our species , Our planet to be unique, Im strongly convienced that we're the only life in our universe, That being said, do i think theres Life somewhere else? Yes but not in our universe,
I am talking ofcourse about other universe, perhaps -besides us- tehres no-one else out there in our universe if so!That would suggest that in a parallel-universe Earth is lifeless, Yet the universe is timing with life.
Most people seem to think that there MUST be life beyond Earth. Given the great enormity of our rapidly expanding universe it does seem probable that there could be extra-terrestrial life somewhere in the depths of space. However probability is not certainty, it merely gives favourable odds. It is quite possible that we are in fact alone. Stars explode throughout the universe all the time (Supernovas) and some create a solar system with orbiting planets, not unlike ours. However, to create life on a planet it takes far more than just the explosion of a Supernova. If we consider that Earth was placed to an exact distance of the sun so not to burn or keep it frozen, but just enough so its ice could melt, inducing its environment (carbon, water, oxygen) to harness the sun’s rays to create and sustain, we start to realise that this was quite an astonishing achievement. In addition, the Moon is also perfectly position so that tides and weather on Earth can be controlled. In fact there are many symbiotic elements that have help form life on Earth. So whether you believe it was God or just a freakish cosmic event that created our Earth, one thing’s certain, it definitely wasn’t easy or a common occurrence. Otherwise by now we would have found newer and older life forms out there. Yet, even with Hubble looking 10 billion years into space, we are still struggling to find even the most basic of hint of life out there. So Earth may well be the only ‘living’ planet……it is possible.
If life existed elsewhere, there would be some kind of remote sign. There has been absolutely no sign of any kind whatsoever. Some people may argue that we haven't been far enough in the Universe to say for sure, but it just would be some kind of remote sign, something.
Since it is all about science, while science means logic and logic comes with at least an evidence, therefore no life exist outside the earth. Do not expect me to believe it just the way it is because science is not a religion, it is not something illogical where you don't even need any proof to believe it. Believing that there is life outside the Earth without any evidence is just the same thing as believing in God which is called hope.
The statistical variables involved which account for the life we have on earth, is beyond the available number of planets in the universe that are likely to have similar characteristics as earth's. Furthermore, it is entirely unreasonable to assume that any other molecules, other proteins, can aggregate the kind of information systems that life on earth clearly represents. The bewildering stroke of chance that life here represents cannot have occurred anywhere else, unless what we have is an infinite universe.
There is no proof of life on other planets. God created this world maybe you cannot understand why the universe is so big but maybe our creator have a great purpose. Maybe he created the universe for us to explore. Maybe there is no universe and what we see are only pictures. No body can understand something infinite since our brains are limited
Yes we are unique.
1. There is no evidence that life exist beyond earth - no amount of marketing will change that fact.
2. The laws of nature is perisistant throughout the universe - same matter exist throughout the universe.
3. If life existed it would experience the same problems - population growth.
And in any case if it exists, then let them come and look for us. Safe our resources and solve our existing problems.
There is no evidence that supports the idea.
1. There would be a lot of noise - signals.
2. The same laws of nature persists throughout the universe - matter is the same.
3. The problems would exist - population growth and intelligence.
And in any case if it exist spare the resources for poverty and let them look for us.
Because there is not water sun outside of he earth, the holly kur,an said Allah said we make the earth mate ad the sky building that is the reason so don,t ever thing there is life exist outside of the earth ( because Allah never tel lain, so there is not enough sun air and water exist out side of the earth
The "evidence" supporting life on other planets is heavily biased. The chances that life on other planets are very slim as the things that have happened on our planet are highly unlikely to have happened and even more unlikely to have happened on a planet that is capable of supporting life.
God created a perfect planet for us such as: Right size, right distance fron de sun, water, oxygen, etc. If you analyze the Universe you can find out that the Universe helps the Earh to harbor life, that means that God created the Universe for us. No nore life outside Earth. My opinion is that we do not have to spend time and money trying to find life in other planets.
Belief in aliens is akin to stating that mermaids exist. Since man exists on land then man should exist under water? It is more likely that there is a form of existence that we are not aware of that exists on other planets ~ but it is unlikely that it is in the form of "life" that we know it. There were many chance (or by God, if you choose) occurances that led to life on this planet. Could those occur again? Yes - but for a planet to have the elemental makeup necessary for that life to be as we currently understand it is highly unlikely.
I disagree that life exists outside of earth only because there has not been any encounters. Even though people think that anything can exist, since there has been zero encounters or any evidence, it is difficult to believe that there are life on other planets. However, we might just not have the technology to find out. There have been sightings, but none of them proved anything.
