we happen to be in the sweet spot where water is a liquid on our planet due to our atmosphere and distance from the sun.
lucky us
mars did have life at one point it seems when it had liquid water
there are certainly other planets that support life, will we ever meet the inhabitants? probably not anytime soon if ever

There may be many other planets that can support life. There may be planets on which intelligent beings have evolved too. We just don't know which ones they are. Its a big universe. The capabilities that human beings possess today, do not allow us to reach out to those other worlds and explore them. But some preliminary steps have been taken in that direction. The laws of nature allow the existence of such planets.

As far as we know, the universe is endless, as is time. So, it is almost certain that there are millions, if not billions of planets out there that have had, have, or will have life in the future.
We know practically nothing about the Universe (I don't mean the physics).
Imagine our galaxy as an object the size of an atom, at the centre of the solar system with the size of the Universe now extending out to Pluto.
Get the scale? No you don't, the Universe is millions of times bigger than that.
Now, does it really make sense that we could be the only place in all that space that supports life?
I don't think so.

The universe is very large. How do you know Earth is the only planet with life?

Because according to some popular theory, the simplest life spotunausly occured from inanimate elements. The chance of this happening are extremely small, almost zero, due to all the special conditions needed. This is why Earth is the only (We know of) that supports life.

WWhatever in the Universe gave you that silly idea? Have you actually *looked* at all of thos eplanest up there? How do you *know* they can't support life?
Would you believe that there bacteria ('life') right here on Earth that life in several hundred degree water, under several thousands of atmospheres of pressure, in total darkness, and digest Sulpher?
You need to rethink that silly question.

we dont know if earth is the only planet which supports life!
basically its all down to the chemistry.

I believe that it is a statistical impossibility that Earth is the only one that can support life. As Carl Segan said: "The universe is a big place, if it is just us, it seems like an awful waste of space."

Earth is the only one science has found so far, but remember...there are other solar systems out there yet to be explored. The problem is our technology. While they have seen at least one other solar system, either by probe or by telescope, our problem is exploring all this is that our technology isn't caught up enough for us to do all the exploring we'd love to do.

How can you be so sure, there is no life of any form out there, just coz it doesn't resemble the life forms we have here. I think we've got a whole lot more discovering to do before we come anywhere near to being able to answer that question.
