Yeah, well, every day is doomsday to someone or something. It's well overrated.
Basic observations that might help: The supernatural is something even dogs with their subpar and small brains can believe in. I don't think the supernatural is worth much attention.
Also, if the Mayans had been so bloody good at math and whatnot, I take it they would have done something about food shortages, declining numbers in population and other issues big and small that brought about their demise.
Going back to the Mayan nonsense after millenia of warfare, research, inventions, discoveries and a sprinkle of enlightenment sends me on a decidedly misanthropic tangent. If people really are this stupid, let them have the apple sauce, the Kool-Aid, the trip to meet Xenu and friends. Just let them.
