It has always amazed me what happened in our history. The Andalusian age of Islam was the repository of nearly all knowledge ever known to man.
They were the most advanced civilization on the planet, light-years ahead of all others and valued higher learning as much as their religion. While medieval Europe struggling through the Dark Ages made little progress dominated by an unyielding and narrow-vision of Christianity. During the clash of civilizations known as the Crusades, which is reoccurring again today, the cultures swapped directions. Islam was almost destroyed and its people returned to backward non-critical thinking while the knowledge the European's learned gave birth to the Age of Enlightenment. Its like the energy transferred when they collided carried with it an electric jolt of knowledge. Sort of like God or Allah said, "You people do not need this anymore so I will give it to these people who do."
Or maybe God saying "If you insist on worshiping this false prophet Mohammed, I will remove my blessing from you, children of Ismael."
I wonder what he will decide about modern America for abandoning Christianity for Communism?
