Are we alone in the universe?

Answer 1

Current information is insufficient to give a correct answer. Once we explore more of the universe, maybe we could have a logical answer.

Answer 2

If we are - it's an awful waste of space. - quote from Contact taken out of context.

I don't believe we are alone. I think there is a lot of life in the universe, but there are lots of different ways to classify something as being alive. Plants are alive as are teeny tiny microscopic organisms. There could be life on Mars for all we know - and we probably will know within the next ten years or so.

When we discover intelligent life on other planets - that will really be something, but according to Steven Hawkings we probably don't want to meet the intelligent life that exists in other galaxies because we are not advanced enough yet. If aliens landed on the planet tomorrow - they would be far more evolved than we are - they would have discovered the ability to travel through deep space, something we Earthlings are not even close to figuring out. According to Hawkings it would most likely be devestating for Earth to encounter intelligent life from another planet, which I find quite sad.

Answer 3

Quote from Stephen Hawking.
It took a very long time, two and a half billion years, to go from single cells to multi-cell beings, which are a necessary precursor to intelligence. This is a good fraction of the total time available, before the Sun blows up. So it would be consistent with the hypothesis, that the probability for life to develop intelligence, is low

Answer 4

With the size, of the Universe, how can we possibly be alone. The odds are, we are far from alone, in the universe.

Answer 5

No - there are billions of people here, so we are not alone!
Actually joking aside, I still say no, why should we be so arrogant to think that we are the only ones around? We may never absolutely know it in our lifetime, but someday in the future a connection could occur in which we finally prove that we are not the only "living" planet with intelligent species.

Answer 6

Seems unlikely. There are lots of planets, lots of stars, and lots of time for others to show up. The chances of there being no other planet, out of all the planets around all the stars out there, where life (in whatever form) is possible are fairly remote. Sure, we may not have any neighbors nearby, and there's no guarantee other forms of life aren't very old or very new, or similar in any way to us, but it seems unlikely that beyond our little globe there's nothing but space, rocks and gas.

Answer 7

The last time I checked there were at least 6 billion other people living with us, so no not by a longshot.

Answer 8

There are so many galexys and plants in the universe that there must be. Every star has at lest one plant orbiting them, all those plant must not be life less.

Answer 9

No, and to think that is very egotistical. The earth isn't the only game in town.

Answer 10

there are billions of stars out there, most with planets . the chances of there being no other intelligent life out there is so small, you couldn't find a number that small. there is life out there, we just haven't gone looking yet.
