So when do you think it "stopped forming," Jack? Care to put a date on it? It certainly wasn't settled in terms of geology, topography and atmosphere after one billion years. It was still a-rockin' and a-rollin' like mad. You could argue that it isn't stable today, but it's as nothing compared to then. I could wish that Mrrzy had said "almost before...", but, like I said, the statement wasn't too far-fetched.
