Does extraterrestrial life exist? Well, I was at the supermarket today and there sure were some odd looking people there. Perhaps they just need to eat more greens or something. But seriously, I find it hard to believe that given the size of the universe that Earth is the only place with life. Given the dumb things that humans do sometimes it's also rather depressing to think we are the most intelligent things around. I reckon ETs out there somewhere.
