converting back unto theism - yes it's true.

You answered your own question with that last sentence there, dude. The Bible wasn't written by God, it was written by men who were writing about God, as they understood Him at the time. To them, since they had seen demonstrations of God's supposed 'wrath' before, it would have seemed very much the sort of thing He would do, ordering the mass murder of babies. God Himself had not changed, merely the men who wrote about Him's perspective of Him.

It's either that or they just made it all up & none of it has any substantive basis in fact (beyond perhaps the occasional, and natural correlation with actual historical events). How about an an alternate explanation. Paranoia and dualism were built in by natural selection as survival mechanisms, and resulted in our predisposition toward superstition and religiosity (along with other evolutionary, psychological, and sociological factors). This is why smarter people tend to be less religious.
