I warn you that this video series is like drinking from a proverbial fire hose. There's a lot of information crammed in here. And beware the specter of cognitive dissonance. Anytime you learn something that challenges your assumptions, you could go into a tailspin until you find a way to make peace with the new info. ((Okay, You've been warned!))
The videos contain all the juiciest information but if you don't have time for an education and your short attention span can't handle date that exceeds 140 characters....you can scroll down and read a few history highlights instead.
Was it "This Day"? If I were God and I wanted to send a message like "Start the countdown" I think this is a genius way to do it. CS Lewis would have appreciated it, I do believe.
