I think it's always worth remembering that the Islamic world kept science, philosophy and knowledge from the ancient world including Greeks and Romans alive at a time when western europe was descending into the barbarity of the Dark Ages. Indeed I'm no expert but wasn't a lot of it housed in a library in Alexandra at a time when Christian Europe was burning books?
This is totally true. But what bearing does it have on the modern world? It is history, it is the present that is important not the past.
