Just guessing, you intended that sarcastically, right?
The NIV says it very clearly (Genesis 6:6):
“And it repented the Lord that he had made man on the earth, and it grieved him at his heart.”
“And, indeed, isn’t the geological record chock full of fossils of beasts which never made it into the modern world?”
So let me get this correct: An omniscient God, with full knowledge of a future failed creation, decides to create said failure anyway, only to decide to destroy it at a later date. That’s not very omniscient.
What absurdity.
I always get a kick out of creationist apologies for discrepancies in mythological stories.
