Comment Aliens? Probably. (Score 1, Offtopic) 94

Extra-solar planets with intelligent life? Probably. Given the sheer size of the universe and the number of solar systems and planets there are quite likely some out there with intelligent life (within range of detection is a different matter). Given enough rolls of the dice you're bound to hit on any given combination more than once.
