I'll just be blunt: You sound like a total fool. If anything, the quoted verse says the very opposite of the point you originally made. The scripture says nothing even remotely to suggest that man was less intelligent after the Fall than beforehand. Your statement was complete BS. Have a nice evening.
Psalm 14:1 "The fool says in his heart, there is no God" Sorry, I don't fit the bill. Matter of fact, I'm not sorry.
