Aliens

Do you believe aliens exist? Based on what evidence, argument, statistics, etc?

What?

The existence of extra terrestrial life is statistically almost virtually certain.

Whether they have visited Earth, I find very improbable.

People who assume that "UFO = aliens" are as dumb as people who think "existence of universe = God". They are both non sequiturs.

That's a really interesting video though.

Aliens probably haven't visited Earth, but they most likely exist.

I love that man. There's a small movement to write him in as president.

If you can find amino acids in asteroids, sugar in nebulas and water in far away galaxies then life should almost certainly exist somewhere else in our universe.

Would you consider people living in a parallel universe to an alien? Presupposing they exist.

Yes.

The undeniable fact that several of the posters on DDO are not from this planet.

Fermi's paradox:

Given how easy it is to create the building blocks of simple life (self assembling amphipathic vesicles, molecules that self-replicate without enzymes, etc.), and given the universe's sufficiently large spatial and temporal size (100-500 billion galaxies existing for 13.75 billion years), we should expect that life has arisen an appreciable number of times and that at least a few of those incidences have resulted in sentient, technological species.

However, given how rapidly technological progress accelerates and given how much time any technological species has had to exist, we should expect most galaxies to be literally saturated with alien technology.

Why then haven't we seen any?

I don't think aliens exist.

Would you want to meet us?

I can't imagine what the benefit would be. If they were even a couple centuries ahead of us technologically (given time frames, the gap is likely to be orders of magnitude larger), we could not possibly have anything of interest to offer them. Consequently, they'd have no incentive to maintain a relationship with us or contribute to our welfare.

The encounter, I think, would be brief, unintelligible and unrepeated with no foreseeable benefit. So no, I'm ambivalent about meeting you.

It's more likely to believe that aliens exist than a personal God exists.

FALSE. The term "UFO" has evolved into a word of it's own which has taken on the widely accepted meaning "alien spacecraft."

Also, even if taken literally, it still means "alien." Why? Because if it were from Earth, someone somewhere on this Earth COULD identify it. Unidentified Flying Object is something that cannot be identified by anyone on this Earth as something from Earth. So even taken literally, UFO means "alien" or "extraterrestrial."

A paper plate soaring through the air is NOT a UFO because one's it comes into clear sight or it lands on the ground, you see it and identify it "hey, just a paper plate." It is not "unidentified."

i think they do and that they visited us. my logic is based on some evidences. you see, some people believe in god but there isnt no physical evidences, but evidences of extraterrestrials with advanced technology exist. i dont believe in coincedences. we didnt even had invented the scientific method till arround 1800. two hundreds year later we arrived to the moon. we already altering the genetics of some species. what makes you think that in another 1000 years we arent visiting other planets and colonize them? it makes perfect sense. people have to start to spread their minds, and see things with logic and objectivity. arround the globe are hundreds of things that cant be explained, or they can but the only possibility is outer life influencing humanity so people are afraid to accept that. go see about puma punku, the golden number in the piramydes etc.. and most important why almost every religion says there gods came from the skies? what the hell? our galaxy has more stars, than our planet as grains of sand. and our universe has trillions of galaxys. come on! do some people really think there isn't outer life! that must be the stupidiest, ignorant thoughts ever! thats like grabbing a cup of water, put in the ocean, and because you haven't caught a fish you say there isn't life on oceans. loool use your brains to think for yourselves.

I've seen UFOs, most of them were probably satellites though. :P

So you're saying that people who call things UFOs are either exceedingly arrogant or exceedingly ignorant, because what they're actually claiming is that they've seen something that "cannot be identified by anyone on this Earth as something from Earth."

Aliens are really strange.

It's possible, but not proven. Until evidence arises, I see no point in debating it.

Because we've never been or seen outside of our own galaxy, and earth is the only planet in this galaxy that we know of which supports sentient life.

Some form of life most likely exists outside of Earth. The fact that organisms can survive in extreme conditions, multiple solar systems exist, and resources for life travel across the galaxy make life possible outside of our planet.

This video pretty much sums it up.

It is a fact that there is life elsewhere in the universe. It is a fact that there is life elsewhere in the solar system.

The big questions are, are we the only intelligent life in the universe, and if we are not alone, is it possible to make contact?

Yes the drake equation comes out to about 3.3 planets per year can produce life but not intelligent life. Stephen Hawkings says that it is mathematically impossible for there to be another life form such as ours beyond this planet. but that is not to say life hasn't existed elsewere before. the universe is not static and ever since the big bang it has been growing until one day in the future it will reach its limits and start contracting back towards a mass and once that mass has enough stored energy there will be another big bang and life will emerge somewere in the universe there too so then we must assume with this theory that there have been an infinite number of big bangs and an infite number of so called earths before ours and will be infinite more to come but leading scientists don't waste time on this theory because they say that whatever occurred prior to the big bang is unimportant and they simply cant observe it or know anything about it so the point is that in 20 billion billion billion years when the universe has contracted and another big bang occurs and another human race exists if we could observe them they would be aliens and to them we would be as well.

Actually, if a paper plate were soaring through the air and was not readily identifiable, until closer inspection it would be an unidentified flying object.

Heck, if we got really close to an alien spaceship, we could just call it "Alien Spaceship" not "unidentified flying aircraft."

People like equating UFO and alien spaceship because lots of official reports have the acronym UFO.

I'd be willing to bet that there are systems where there are dual planets, both planets developed life, and one of them got intelligent and discovers life on the other planet. They might even both be intelligent!

Aliens are also known as extraterrestrial life which means not originated from the Earth. Scientist have found that they exist in the form of bacteria or other organism. Hence, I too believe in Aliens but not those seen in the movies and videos that try to harm our Earth.

The ingredients to life are scatter in great plenty in our galaxy and as such should be prevalent across the universe. When we take into account the misnomer that water is absolutely necessary for life as we know it; the bar widens even greater. What is necessary is oxygen and hydrogen, which water tends to have quite a bit of.
The assumption that there can be no life elsewhere is a self-centered and arbitrary position. So life on other planets? Yes

Life native to space? Maybe, but unlikely.

Intelligent life: perhaps, but also unlikely.

99.9% of our universe exists in an antagonistic state to life. We live in a pretty dangerous place here, and it"s big. Bigger than anything. There is nothing in our existence that is bigger then the universe.
