Stop right there. "WE" haven't seen anything. And WE haven't seen any proof of "2 million years" of anything being seen anywhere.
What WE DO see evidence of, is a sudden onslaught of ice instantly killing and burying a tropical region.
As I said, read the link provided, and after a couple days it will take you to read through the whole book OBJECTIVELY, let me know what you think.
You will find it very interesting if aything else.
At the very least, you will understand a little more about geology, whether you believe in the authors conclusions or not.
And maybe you weren't around for 2 million years, but that's your problem.
BWAAAAAAAAAAAAAAAAAAAAAAHAHAHAHA!
