Exactly, with an infinite amount of sample space (the universe, it never stops...so we think) there has to be some other form of life. However, the chances of there being a planet being created that supports life is very rare as well. Just because we make it to the next star doesn't mean that all the planets won't all be barren deserts or frozen ice cubes. The Earth was the exact distance away to form a proper atmosphere, have bearable weather, not be too hot/cold. The weirdest thing to me is that when you look up into the sky, you see all the stars that some are pretty much at an unmeasurable distance away. Just think of another life form looking up at night and watching our sun. O.O Meh, I had a debate on this for school lol.
