End of world myths (in the sense of detailed but unproven beliefs) are common to most if not all civilizations.

I tend to question the ability of the Mayan empire to accurately predict an apocalyptic event. It was an astounding civilization for its time, with great buildings, an accurate if complicated calendar, etc. However, it also was an empire that was tottering by the time the Spaniards invaded, which allowed the latter to turn neighboring kingdoms against it (an occurrence which its calendar apparently missed). It was a civilization that we believe practiced human sacrifice on a large scale and was mired in superstition to the point that it practically paralyzed itself. I have a little difficuly accepting that these people were nonetheless so in tune with the forces and influences of the universe that they could say with certainty the day it all ends.

If I'm around then, I won't be surprised either way it turns out.
