Islam is at least 3,800-4,000 years old. Abraham's son Ishmael, who was the daughter of an Egyptian maid of Abraham and Sarah who slept with Abraham was the father of Islam. He is the older half brother of Isaac, the man through whom Judaism and, later, Christianity would come. Ishmael always disliked Isaac and things have not changed today as Islam as a whole dislikes Jews and Christians. (I'm not talking about the moderate Muslims who are tolerable to all three religions). So for another religion to spring up on the level of Islam? It could, sure, but I don't see this earth lasting another 3,800-4,000 years to have time for it to mature.

As a student of Arab and Islamic studies, as well as someone with actual brain, I say you know absolutely
nothing.
