Muslims claim that Mecca is in Saudi Arabia, that Mohammad was born there, and that he also received his revelation of the Quran there.  If that is true where is Mecca? Steven Shoemaker in his book Creating the Quran on page114 mentions that there is no mention of a mecca in any of the great civilizations of the time .  Not only that,but another scholar; Patricia Corona said that there were no trade roues going through Mecca on land nor by the coast of the Red Sea bordering Mecca.  Many scholars say that Islam started way north of Mecca and that most Muslim scholars were Persians.  So Shoemaker concludes that Mecca was further north.
