What is with 2012?

2012 is the year the anceint Mayan Calendar ends. The had a very sophisticated solar calander, and according to that, 2012 is the year it ends. Will it??? I really don't think so, but the thing about ancient cultures, they knew a whole lot more about our earth. Their whole civilization was dependant upon knowing certian times and seasons. We in our "superiority" are ignorant.
