A mix of half-truth and utter nonsense. You clearly haven't taken your own advice on referring to the history books before posting rubbish.The church didn't create the dark ages! The dark ages were created by hordes of armies destroying multiple civilizations and leaving Europe in a state of constant warfare. Remember the Romans? The fall of the Roman empire heralded in the dark ages. If anything the Church held the light of scholarship throughout those barbaric times and maintained historical accounts which are still used today help understand the dark ages better. The church was one of the only lights throughout the dark ages. Cluney Abbey and other such places are good examples of this. While the world was falling to crap all around them, the church was one of (if not the only) places of refuge for the crapped upon peasants of the day. This doesn't just apply to the Christian church either.
With all due respect, refer to any history book on the subject of the dark ages before writing any more of these kinds of OPs
