does anyone believe in the dec. 21 2012 theory?

ok we were tlkn bout this n my physical science class last yr. idk tha name of tha calender mayan or something but everything that was predicted on that calendar did happen on that date
 
I think it a bunch of bullshit because they have predicted other days before and it has not happened so we will have to wait and see. I sure hope it not the last day because 2012 is my last year in high school. Bach to the winter riding I have done so much of that when I ride for no lie 10 min. I loose complete feeling in my thumb.
