Was Islamic prayer created under a "flat earth" umption?

I wouldn't be surprised if most Muslims actually believe the world is flat. Muslims are notoriously uneducated. They force their children to memorize long winded tracts of a primitive old book of nonsense sayings and stories. They whip them if they don't remember it. Muslims encourage their children not to think, just to remember verses from their stupid holy book. It is a truly ghastly religion that should be shown no mercy or tolerance.
