Has no one really considered that maybe, just maybe, 2012 was the year they decided they'd stop writing a calendar thousands of years into the future for? Maybe one of them was like "Hey, we've got a couple millennium until we catch up the calendar, lets stop writing it and do something else now."
Don't forget that they didn't even see their own civilization's impending doom. I liken this stuff to psychics in general; why not play the lottery?
