Moslem thinkers had different ideas long ago but, of course, the Koran trumps all. I even brought that up when I was actually trying to discuss things with a Moslem in who had the shop next door to mine 20 years ago. I thought he was being friendly. He got very evasive and wouldn’t actually answer the question about the shape of the earth. Not for that reason, I don’t discuss anything with Mohammedans anymore. It is pointless. Ultimately the only thing they will discuss with an infidel is the infidel’s imminent conversion.
In Saudi they have only translated some 100 book to Arabic: Everything that they think they need is already in their book. In a generation or two they will be back to the camel age.
