Are you saying that God made a mistake when he created Neanderthal Man and had to keep creating Man until he got it right with us? If God didnt use evolution, then why did he screw up with all our forebearers like Neanderthal? I dont read anything in the Bible about Neanderthal? Are you saying that God didnt create him and that he was a work of the Devil?
Actually the Bible does talk about the "giants" but doesn't say where they came from. And a lot of people think Neanderthals were humans so I don't see a problem.
