What if we are alone?
Here's what we know about whether there's life in the universe outside the confines of our planet: nothing.. nada..zip. Well, at least so far. Maybe some day we'll discover proof of life out there, or maybe not. To Ramz' point, there's a possibility that our biosphere supports the only life in the universe. Or, we're just the first to develop. Think about the fact our "known" universe is about ninety-some billion light years across. Perhaps little green men live at the other end and we just haven't caught sight of them yet. And I'm not ready to buy into divine creation as there's really no evidence to support that premise either. As to the guys back in '52 stirring up some chems in a Petri dish, or whatever, and attempting to create the spark of life, I don't think that demonstrates a conclusion that we can just say "well, that didn't work.. guess it can't be done. Let's move on and break for lunch..". Perhaps it takes thousands or millions of years for organics to stew in an environment where all the right ingredients gather and ignite a primitive life form. LIke I said, we just don't know...yet.
