Has human nature changed over history?
Human nature has not changed over history. The human race has remained the same for 6,000 years, and corruption follows a consistent pattern: as people get corrupt, they get more corrupt, and then they get even more. Religion has always operated this way, with those in higher echelons feeding off the income.
Les explains that the human race hasn't changed one iota in 6,000 years. He points to the archaeological evidence of Caiaphas's house, where multiple layers of costly wall materials showed the wealthy lived sumptuously by feeding off the income from that religion. He notes that religion has always been that way, and if you look at any religion on the face of the earth, you'll find the same thing in the higher echelons. As people get corrupt, they get more corrupt, and they get more.
