In his mind, if Negro evolved from monkeys, there should be no monkeys. The sleazy Southern Baptistic preacher knows more most astrophysics than author Hawkins. He thinks it's impossible for "things to be created by explosions" thence the Big Bang Theory is false. The mortgage broker knows more most Economics than nearly everyone who studies it for a experience or who has chaired the Congressional budget committees.
