“Waters and lands have been “rearranged” in times of colossal cataclysms since man first appeared full-hatched.”
Yes, but in Genesis 1, there was nothing living when it all started. Only a water submerged planet. That was not its original state.
Some theologians think it was destroyed in Satan’s rebellion. He was in charge here, at the time.
IOW, such theologians believe it, based on absolutely nothing. That's why theology isn't science.
