Naaaa, it won't end in 2012, there's no proof of it.
And, I don't believe our Solar System is going any time soon, theories that it will collapse in on itself and all that, in my eyes, is nonsence, there's no proof to say so, we can't tell the future, so there's no way of knowing.
BUT, man will eventually destroy earth, and then we'll all be on another planet somewhere else.
Who's to say that didn't happen before? That people weren't here before us? or some sort of life form(s)?
People are already moving out, in fact, NASA is planning to send out a capsule with a few people in it, into the atmosphere, that way, they'll be able to tell if its possable for us to survive somewhere else in our Solar System.
If we can't survive anywhere else, whats to say different life forms can't either? People say that "Oh we can't survive people we're "such and such" a distance away from our sun", life forms that are adapted to different environments than us?
Thats my belief anyway. I think its all one big cycle.
