Well, I can't prove that the guy is wrong, in the same way that he can't prove he is right (although he does make many mentions of his theories being the only possible solution). However, he does say some rather ignorant things regarding the speed of light, and "conveniently" gets his numbers wrong when proving his "divine ratios".
Whether or not I belive in God really does bear no relation to my belief in science. It is perfectly possible to believe in the two, one on a purely physical level, another on a spiritual. However the problem Creationists have is that they constrain themselves with religious literature. If they just thought "What if, just maybe, the Good Book is for spiritual guidance, not a definitive scientific text?!"...
Would you read an interior design magazine and then try to extrapolate from that how a house is built? Of course not! The magazine tells you how to decorate and live in the house, but it doesn't mention bricks, mortar, sand, cement, plasterboards, studwork, wiring, piping. If you tried to, then you would end up saying "The walls are made of paint. This is the only possibility because the magazine doesn't say there is anything underneath the paint. All it mentions is paint on the walls. There is nothing beyond the paint. Just paint."
Of course I could be wrong, but if this guy can prove he is right, then you better keep the paint-stripper away from any walls you want to keep.
