Let's say you're trying to explain that concept to someone who has no idea what a prefrontal cortex is and no way to figure it out, such as someone living 5,000 years ago.
Would you...
A. Come up with a version of what you've said here that requires no knowledge of the prefrontal cortex (such as "When God made man's mind much greater than the inds of animals, etc., etc.")
B. Spend 1,400 words telling the person about a universe being created in a week, followed by a woman being created with rib surgery and deceived by a talking snake? Don't forget this version has to include the idea that plants existed on Earth before there was a sun.
It's very likely you'd choose option A. So why would the infinitely wise Almighty choose the ham-handed option B?
Possible answer? Because option B is the truth.
My opinion is He inspired ancient man to write option A so that when the gift of intellect finally allowed us to understand how it really happened, we could look back at Genesis and realize that an ancient man couldn’t have come up with that allegory unless inspired by God to do so.
