The disconnect between the bible, and its horrific actions versus the message

A modern retelling might involve a bomb shelter and a nuclear apocalypse.There would be an awkward moment a few months after they left the Ark once they realized who their kids' marriage prospects are. Family reunion turned singles mixer.

Really? God wipes out billions of people, and from this you get the impression that God won't ever give up on people? The Noah story is a rather obvious copy of the Utnapishtim flood story in the Epic of Gilgamesh. The story in the Epic of Gilgamesh has an ark with family and animals, birds finding a branch after the flood, and a rainbow after the flood. The Noah story appears to be a retelling of a known story in a Jewish context with undertones of cultural appropriation.

That's not the point I get from the story. God gave up on a lot of people, those who weren't the one righteous person. God is telling us that if you aren't righteous then he will give up on you.

No one freely chose to drown. That was forced onto them. It's normal human behavior. We do it all of the time. Haven't you ever watched a movie? We are talking about a Creator who went out of his way to kill people. No one chose to die. The Creator chose to kill them.

This was especially so in the Exodus story where God killed the first born as punishment for Egypt's leadership not freeing the Hebrew people. Takes a special kind of evil to kill peoples' children for not doing what they tell them to. And it's not as if God has something against slavery either because he allowed the Hebrew people to put foreigners into chattel slavery.
