If I had the time, I'd make one of these crossreference rainbows for the OT/NT and the Book of Mormon, just to embarrass weak-faith Christians who think this chart means anything. This would only be "proof" of something if the writers of the sequel had no access to the original.
Also, you can't "prove" God, and it insults His Name to try. If He wanted to be prove-able, there would be proof already. He either wants us to rely on faith, or He doesn't exist. Either argument makes more sense then any of these fake "proofs".
