Why is it people who claim to have been abducted by Aliens invariably claim to have suffered examination via Anal probe?
Surely if an Alien can travel light years across the galaxy they can figure out the workings of a human being by more technology based solutions rather than sticking something up a drunk red necks bum? Or are they just a bit kinky?
Maybe they aren't analyzing the human body, but how we react. So maybe they want to see how a homophobic redneck reacts to something up the pooper.
The chance of life being created is such a small possibility that I think its possible but far from definite, but with randomness there is the chance of something unlikely happening a lot so life could be all over the place.
The question is if any life can get intelligent enough to escape a system and sustain their life before their sun explodes. We keep getting more and more advanced but there is a chance we will a) kill ourselves or B) hit a brick wall where we cant sustain life indefinitely away from earth and as such are doomed to stay here until the planet or the sun kills us.
But I'm not a scientist so fudge knows.
