No, and the Mayans didn't think it will end then either. It's just the end of their calender. Their perspective is that Dec 21, 2012 is the tipping point, that by that point the majority of the Earth's population will have to have come to the understanding that we need to live in harmony with the earth to survive.
yeah they sucked the only managed to to create a fully developed written lagnuage, a calander, mapped out space, managed to figure out what to do with crops, built temples without metal tools, created a number system which included "0" , insane architecture etc etcALL mushroom driven heheheheIm guessing probably a plauge wiped them out. Or maby what happend to the romans, the older innovative generation died out and generation nothingness ruined it all
and how do you know exactly what they meant? since no one else seems to..?
