The end of the world?

The end of the world?  Why would anyone give any credence to anything said by the Mayans?  They were a disgusting group of people if there ever was one, practicing human sacrifice and probably poor dental hygiene as well.  Why do you think the Spanish were able to conquer them?  The other tribes cooperated with the Spaniards, probably having gotten good and fed up with the Mayans sacrificing their members.

Just because people lived primitive lives a long time ago and are now extinct does not give them a Get Out of Jail Free card. Some indigenous tribes were pretty rotten in their day.  Good riddance to them and all their works.
