I do Not mean to imply that the ancient people, the sons of God, were any different than ourselves. They looked the same, could produce offspring with Humans, and were the pinnacle of evolutionary growth BUT they were Not Human. Noah is the Missing Link between animal and Human Intelligence, on this Planet. That's God's Truth, not mine.
Ah. I see your game: you've decided that "pre-Noah" humans are not human. Any evidence that I provide of ancient peoples will be dismissed as being from these creatures that looked like humans and could breed with humans, but for some unknown reason have been defined by you as not human. It's a warped version of the "No True Scotsman" fallacy.
I doubt I can give you any evidence that would be able to convince you, but that doesn't mean that human intelligence didn't evolve naturally.Bring forth your evidence that we evolved our Human Intelligence naturally, in contradiction to God's Truth. You cannot, and neither can any other person with a real interest in knowing the Truth of the Creation.
