I've never heard anything explained this way. I found it quite interesting and very refreshing. We only know of our now, our present. How can we possibly know that very far back? Everything is basically scientific guesswork based on what we know about our current environment. Who's to say it wasn't so very, very different in our past? No one really can. It's all theory....unless one actually lived then, and none of us did. Do not be so small to not open your mind to a great historical accounting. The only accounting that was actually written down and preserved by man. No matter, you're choosing to believe one man's theory over other's written accounts.
