that is true, but the mayan's believe that 2012 a change in the world is coming, now for those who don't beleive this they have predicted the calendar and the changeing of the moons etc; so i wouldn't count them out
but also normally they believed when the changes came they would build another pyramid to pease the gods; thats why their pyramids are build on top of each other. so it may not be that bad
i personaly don't believe in the Vatican theory though... i think the answers to this world aren't anything you will find on a scroll locked in a vault, but probably something we have seen for millions of years but have never realized it was there.
