there's only one level: allah will rule the whole world and mohammad is the last 'prophet'
Your position is that being a Muslim implies blind allegiance to a singular philosophy, and that simply does not line up with the facts.
I am not in any way defending Islam here, but your putting brilliant minds, educated in Greek philosophy and thought, in a tiny little box just doesn't wash.
But, I have no doubt that there is no amount of evidence that will change your mind, so I'll end this now.
