After the first 15 minutes there was no point in debating anymore. Ham's logic was you weren't there so you don't know. There is no possible way to debate that. If you're going to throw all logic out the window and say that the laws of the universe don't apply if you weren't there then the debate is over at that point. All I would have to say is that god is one hell of an architect, physicist, biologist engineer, and construction manager because that was an awful lot he got done in 6 days. Just placing light sources and then placing their photons across the universe is an unfathomable task in and of itself, especially considering it must travel billions of light years to propagate on it's own.
