The Mayans predicted change or possibly of what people say the "ending" of the world. Do you believe this? or do you just think they were warning us of the change of the world and our ways? what do you think?
geologically speaking, this has happened before, but humans weren't around at that time, so nothing is recorded.
we've had end of the world parties before(1984, 2000) and this is just another reason for alot of religious fanatics to go off the deep end.
i believe that huge geological changes will happen, but as for the end of the world no, not at all
