Then why is Cain described as a hunter, as opposed to Abel who is a farmer? (Or do I have that backward?) Was he just hunting for trophies?! Why all those dinosaurs and other carnivores (supposedly buried by the flood) with big pointy teeth, and in a few cases with the bones of their prey still inside them (and even more commonly in their fossilized dung)?
This notion of yours seems pretty nutty, fully on the plane of the flat earth theory.
