I thought the 13th Bak'tun of the Mayan calendar just marks the end of an epoch, much like how around this time we left the Age of Pisces and entered the Age of Aquarius.
The Mayans would have been partying, not preparing for the end. There is no scientific literature pointing to apocalypse predictions. And here we are, still alive and well. Seems like the koolaid drinkers never want to hear scientific info though. Maybe it's because they need a personal apocalypse for their miserable lives.
