Personally, I dont believe any one theory. Mankind may end, or maybe it will just be the end of an era. Maybe 12/12/2012 cwill bring about the complete understanding of the human brain, or even the discovery of the encoding of a soul in DNA. The Mayan calendar could just be a countdown to the return of the alien race(s) that provided us with our technology, or it could just be that the creators set a goal for "lets at least get to 12/12/2012, and we can start on our next project."

A quick side note, did anyone watch that one documentary about the book "Chariots of the Gods"? Interesting food for thought.:thumbsup:
