What if the Mayan "scribe" whose job it was to keep track of the calendar simply got writer's cramp--I mean, perhaps he just quit writing, and it happened to be on the year 2012. Maybe we are over-thinking the significance of this date. Also, did not the Mayans practice ritual human sacrifice to "appease" their gods? Somehow, it doesn't seem to fit the bill of an advanced civilization, at least not in my book.
