are we the only livig organisms in the whole of the universe?

Answer 1

Considering the shear immensity of the universe, it does not seem possible that Earth could be the only place where life can thrive. There is life out there, the question is how far do we have to travel to find it? It could be 100,000 years before we discover extraterrestrial life, it could be 2 days. For all we know their could be microscopic extraterrestrial life within our own solar system.

Answer 2

Possibly. We have no direct evidence to the contrary. We are just starting to look for evidence of life in the rest of the solar system but its pretty obvious we are the only intelligent life here.

We've seen indirect evidence of planets around many other stars, mostly in very inhospitable configurations, but that suggests that a substantial number of stars have planets. And even though we've only found life on one planet, it is 100% of the planets in the orbital zone most habitable to our kind of life. If we knew exactly how life got started here, we'd have a better tool to predict life elsewhere.

The odds are very good that there is life out there somewhere, but we don't have any examples. It's like calculating a bet on a roulette wheel that has never been spun. There has to be a first time before you really know anything.

Answer 3

of course not ! I'm not so selfish to think that we are the only planet with living organism.
Recent discoveries in the Archea phyla showed incredible adaptations of this living organism to extreme (for us) conditions, like hydrogen eating, methanogens and methane eating, sulfur reducing extremofile, radiation and dessication resistant bacteria.
Some of them can really be transported to mars and survive without problems. These kind of metabolic pathways were completely unknown like 10-15 years ago and were only supposed by some sci-fi books/movies.

So I think that life is just common through the universe, but thinking about humanoid aliens here...well is just a delusion.

Answer 4

Of course not.

There are too many galaxies in the universe to think that we are the only living organisms.

If an alien living hundreds of light years away saw a picture of the Milky Way, would they think that anyone lived there? Probably not, but here we are discussing this on Yahoo Answers. =P

Answer 5

No there are others - right here on planet Earth!

Seriously though there may be 200,000,000,000,000 planetary systems in our Universe, if only a small % have life then its likely to be teeming with inhabited planets. Whether they're intelligent or not is impossible to know but I doubt very much that we're alone.

Answer 6

No. The Universe is full of life. It's just waiting until we can handle that information before dropping in for a chat!

Answer 7

In this universe, there are many planets, stars etc., but up to our knowledge, we know only one life supporting planet i.e., earth. But latest news says that there may be water traces on mars...so there may be life existing there. And even life may exist in another planets (not in our solar system) even though they doesn't support life, because there life may be living in different conditions. Don't think that I am writing fiction stories. Remember that previously, traveling in air, cell phones, computers, space journey, landing on moon are all fictions only. But now....they are all became real....

Answer 8

in this universe their are billion galaxies and every galaxy have billion stars and it have its own planet and it also had a life we cant say that we are alone in this universe different organism diffetrtent needs,different organisms structure,differrent way to live we cant say that we are alone.

Answer 9

till now it is a matter of conjecture. However,the way humans are behaving presently,there won't be anyone to pose this question sooner than later.

Answer 10

no amoeba is also living and there are more than 1000 of livin organism
