NO,WE ARE NOT THE ONLY ONES IN THE UNIVERSE,WHO EVER SAID THAT IS A IGNORANT,HUMAN HAVEN'T EXPLORE .1 OF THE UNIVERSE,WE ARE STILL IN MARS....JUST IMAGINE THAT\nAND ANY KIND OF LIFE(PLANTS,INSECT,BACTERIA...ETC)IS CONSIDER AS E.T

Using mathematics to determine the chances of life elsewhere in the universe, one estimate determines that there are approximately 10^75 advanced societies.  If true, then it is very likely that there is life beyond earth – even advanced life forms.\n\nSteve\n:-D

Absolutely not and I think it would be incredibly arrogant of us to think we are the only life in the entire universe, considering how many billions of planets, if not galaxies, there are.  There are more that can sustain life.

I wouldnt say there isnt any life outsdide our solar system. there can be a very high possibility that there is inteligent life out there.

Why is there life?? If there weren't we wouldn't be able to ask and answer questions on yahoo answers!

There is alien  life. Perhaps not in our solar system but definately out there.\nNow this life could be simple microbes or anything like that.\nIntelligent life may be out there too, it all depends on how things developed after the big bang. There   MUST Be intelligent life out there.. There's none here!!!

Come to think of it... we all know that our planet is an insignificant speck circling an ordinary star, far out on a spiral arm of the Milky Way Galaxy, which is an ordinary congress of a few HUNDRED BILLION stars among at least a HUNDRED BILLION GALAXIES!!!\nWe are still the only intilligent life we know of anywhere. But now humankind has taken a dramatic leap towards a possible demotion. Planet-hunting scientists and astronomers world wide are refining their technique in detecting other planets in far off stars & galaxies. who knows that one day, we may be able to find a world that is much like ours?\nFor now, humanity can bask in its special status as the only life known to be contemplating such questions. Many scientists predicts that this distinction, too, will crumble. But the search for other worlds is not only a quest for kindred intelligenc. it is also about the destiny of human species. Where are we going to be a hundred million years from now? Where will we go, and how will we get there? And how will it change who we are? _end

Of course we're not. How truly arrogant of human race to think we are the only life in the universe. There are billions of star out there with billion of planets. There is no way we are the only ones.

I doubt that Earth is the only planet in the whole Universe that can sustain life.  There will probably be some other planets out there somewhere with some sort of life on it.  Whether it's intelligent life or not is another question!\n\nThere may very well have been life on Mars, or on other planets in our solar system at one point,  but we have yet to find it, or any evidence.

To believe we are alone in this vast universe is simply naive. Either micro-organisms to superior beings something is out there somewhere

Depends on what type of life you mean. Human life, No. Humans only exist on earth and other space stations where technology has propelled mankind to.

How can we be alone?\n6,487,053,332 humans moving on the planet (http://www.census.gov/main/www/popclock.html) and u say we are alone!!!\nJokes apart... there is enough probability for life to exist in the universe.... if we are existing here... then there can be some other organism existing elsewhere...\n\nDefinitely there is life elsewhere... only problem... it'll take time to find them out...

I once read a theory that the universe is so big, that there's a chance that not only is there another earth somewhere, but there's probably so many that there's bound to be one exactly like ours.  The universe is huge beyond our present ability to comprehend, and it would be highly ignorant to think that with all the building blocks of life floating around out there that life doesn't exist somewhere else.  Whether we ever find it or not is another question.

Alien? What's that?\n\nI think there is a huge statistical probability that LIFE exists somewhere else. And that may be as simple as uncicell forms of life. It may also be another form of life we've never seen on earth.\n\nBut "aliens" as we see in movies, sure not!!!

Sure why not.\n\nJust look up in the night sky. There are so many starts we can see, and untold planets we can't. This is just one galaxy. There are so many more out there in the univers. It is really silly to think that with all those planets, ours is the only one that has life.\nOur planet is still a young one. I'm sure there are life forms on other planets that have technology we can't begin to comprehend

Yes, I fully believe there is life on other planets.  What it took to create life on Earth was not favored to happen.  The odds that Earth would hold any life at all are too small to comprehend.  But we do not know how large the universe is.  We do know that there are trillions of planets, trillions of galaxies, trillions of stars.  The odds that there is not a speck of life on any of those planets is also extremely small.\n\nI must admit that I have seen a UFO, which occurred last year.  I was driving my friends home from a party and I happen to look in the sky to see a bright white diamond-shaped object.  There were four individual diamond lights that made up the overall shape.  I was astounded, and I knew it was not anything that the United States had admitted to having.  I could name every military jet, helicopter, blimp, and passanger aircraft that I see, but I could not for the life of me figure out what it was.  I immediately turned around and drove to follow it.  Within five-ten seconds, the craft had flown so fast that the lights had disappeared (I watched it the entire time).  I'm not saying it was extra-terrestrial, but it was a UFO.  I live in Cleveland, by the way.
