The mayans were such geniuses they couldn’t foresee their own demise. So of course their calendar end of the world is believable. Duh.
Morons.
Yes, I agree. Their magic calendar didn’t foresee the fact that for practical matters, they would become extinct.
People who give these ghost stories any mind are silly.
But we are so smart today we still don't know what happen to them. That space guy that helped them may have known something.
Of course this is all bogus, but I think I read somewhere that they did predict their own demise. I remember that from something I read as a child so take it for what it is worth. :)
