Given the nature of technological advances, mankind is at the brink of establishing contact with an advanced intelligence from a nearby star system. This unique event the will catapult and unite mankind into exploring the universe to learn more about how life evolves on earth-like planets within our stellar neighborhood.
The odds of us being alone in a universe that is infinitely expanding, infinitely gaining new stars and solar systems, and infinitely gaining new possibly inhabitable bodies is almost infinitely small.
We have good idea about the number of planets in the galaxy, and while I cannot remember what that number is, it is pretty large. There is bound to be *some* non-earth planet out there that is in the Goldilocks zone and has all the other ingredients for life. It would be more improbable if there wasn't another earth-like planet than otherwise.
However, I think that this discussion should not focus on life-sustaining planets, but on whether or not civilization could survive long enough to meet ET. In other words, we should be talking about the L part of the Drake equation, or whether species of intelligent life are prone to nuking themselves out of existence. I, personally, am optimistic about this.
There has to be life on other plants, and it's just a matter of time before we make contact with other beings on other plants. The government needs to reopen our space programs, so we can explore more. Their is a need to explore, so we can find out what is waiting for us.
To think that we are the only living things in infinite space is egotism, to the highest factor. One day, we will make contact with other life forms.
Given our current technology and the rate of advancement at which we discover new technology, we should be able to locate other beings that inhabit the universe in the very near future. If not us, it is totally feasible that other beings will make contact with us first, if they haven't already done so, based on UFO sightings.
With that being said, do I think human will ever make contact with extraterrestrials beings? Probably not. Considering the history of human species, coming from a single cell organism into a well developed species with ability to search for life beyond our planet is a very special transition. Millions of other species that co-exist with us, some have been here much longer than us and even if they survive another 100 of millions of years, they will never be able to develop a way to contact with extraterrestrials from another planet. It is futile for us to try to get a respond from these unintelligent creatures even if they do live on some habitable planets. Furthermore, the gaps between space is unimaginably vast and with our current technology, we wont be able to cover much of the universe which limited our chances to spot an extraterrestrial beings.
its impossible to have an opinion on something we have no idea about
