Well, the Universe doesn't just spontaniously create life whilst expanding. The matter that is here already is the matter that has been here since day 1. I find it highly unlikely that there isn't another planet out there that is very similar to ours. I know our planet in itself was a miracle, being that if it was off by X measurement, life wouldn't have been possible...But there's gotta be another one out there. :P yeah but the bigger the universe the bigger chance there is of life being out there. if the universe is endless then so are the possabilities
