Well there goes any hope of a actual interesting thread for once staying interesting. The topic is a good read though, The Myans were way ahead of any other civilaztion they say by thousands of years, so this is why some take this calander so serious.

If you want to really judge how they say the 5th world ended in 1987, look how daily life, how safe the world was, etc all ended at the end of the '80's (Kinda right on target with what the calander says)
