Not rejecting God or the Bible. Rejecting someone’s interpretation that snakes and by extension all other predators were nothing of the kind until Man fell.
It was only after the flood that God put the fear of man into animals and vice versa.
Also, the edible bits.
“Rejecting someone’s interpretation that snakes and by extension all other predators were nothing of the kind until Man fell.”
Well, that particular notion is “someone’s interpretation”, but the idea that there were no carnivores prior to the flood is not. That is straight out of the plain text of the Bible, no interpretation required.
