Mayan Calendar

End of the World?
Evolution?
Other crackpot theory?
Or, just the end of a calendar?

Does the world end when you have to buy a new calendar?

Occams razor; The simplest solution is usually the best.

They made a calendar out of stone, using their math system, limited by the space available on the stone chosen. They probably expected this generation to maybe... be able to make a new calendar?

Aliens, World Ending, Apocalypse, or just an expired calendar? Which is more simple?

If I hear any more about this I think I'm going to have to start ranting about the percolation of stupid in our colleges.
