so let me just figure this one out....
everybody thinks that the world is going to end on 12/21/12 because that is when the mayan calendar ends.
in modern times, we have calendars as well.
what do we do when our calendar ends? does the world end with some sort of horrible disaster and lots of death every december 31?
NO! we just get a new calendar on January 1.
so if the mayans had been around until 2012, i am sure that they would just make a new calendar, and the world would keep on truckin'.
