Then there are parts of an anomalous Torah ~ where facts about the past are just flat out different than the standard Torah in use in modern times (last couple of thousand years anyway).
Parts of the Koran are clearly just history ~ of somebody ~ presumably a fellow named Mohammad who may or may not have been a religious reformer.
More recently the Saudi Arabians conducted an enormous archaeological study of the Kaabah ~ the big factoids are it's pretty old ~ predates Islam, and was for the most part a Hindu Temple dedicated to the worship of a sort of snake god ~ who was NOT Krishna ~ yes, there are other snake gods. Shatan worship uses a snake; Satan is depicted as a snake; Moses used a snake; American snakehandlers are pretty much like Methodists theologically speaking, but they use snakes in worship services. That pretty much covers the waterfront.
National Geo covered the archaeological digs.
No, the snake god is not the Moon god.
On the other hand the minaret predates Islam and is the male member of the Earth god. Yup, Arabs had a masculine Earth and a feminine sky. Most others do it the other way around with a feminine Earth and a masculine sky. That, BTW, is one of the more ancient observations ever made about Arabian beliefs.
Regarding calendars, Islam makes use of the lunar calendar ~ so did the ancient Chinese ~ and then there are siderally adjusted lunar calendars ~ none of that turns you into a moslem ~ just screws up Easter and Passover.
I subscribe to the idea that mohammad was a great conqueror. That much is clear. I also think it's reasonable that he saw what happened to empires once their leaders (in this case him) died. They were broken up and conquered by someone else.
His rather absurd religion does a good job of keeping the empire together (convert, pay a “tax”, or die).
I don't know if you're arguing that islam is somehow a legitimate religion in the same way that Christianity or Judaism is legitimate, but I don't buy that idea. It's clear - by their actions - that muslims are lacking in a variety of areas. Their actions speak so loudly that I can't hear a word they're saying. Kind of like obama. Actually, A LOT like obama.
I’m pretty sure Krishna is not a snake god. He’s depicted as a dark-skinned human, not a snake. That would be Naga or Nagini (female). Perhaps also Shiva, a Dravidian god in the form of an ascetic protected by a hooded cobra
