Very nice video Walt, thanks for posting this link.
One technical inaccuracy there, it did not explain where the face (man in moon) came from.
More seriously, once I saw a simple artist conception of the Earth a few billion years ago -- a lot like the beginning of this video. It's pretty obvious from common science knowledge that this has happened but the visual of it brought home to me how there was absolutely no life
forms on Earth then. We've come a long way. I sometimes wonder what life forms will be here in another billion years. How will the Earth change physically and how will we evolve physically and mentally?
