A cliche overly asked question I know, but I wanted to hear your views on this as well as share my own. I don't mean aliens who fly around in their UFO's making crop circles precisely, but just animal like life on other planets.
Earth is obviously the only place we know of that has life. Intelligent life that is, not just germs and all that. It's a very bizarre thing really and a seemingly incredibly unique circumstance. When you take it all into account, what's the odds that another planet followed a similar path? It seems slim when you think of it. A planet would have to be in the right place next to its sun, at the right rotation, have the exact same atmospheric forming eruptions occur, be the right age with pretty much everything else being identical to Earth. Otherwise any life it may have wouldn't be identical to ours, or possibly not even intelligent.
At the same time though, if we did find intelligent life similar to ours inhabiting a planet of their own, I believe that would change everything. It would mean to me that Earth isn't unique and went through some one of a kind evolutionary process, but that it was supposed to happen. If we found just one other planet with life, it would pretty much confirm to me that some planets are intended to create and hold life forms.
