Today, with Islamism reigning supreme over Arabia, it is hard to imagine the Arabs without Islam. Back then, most Arabs followed pagan cults descended from Mesopotamian religion, while there were also Jewish, Christian, and Zoroastrian tribes. Any of these religions could have come on top, but then the religion of Islam came with no warning and empowered the Arabs to conquer much of the known world. However, here, we will imagine that Muhammed was converted to Zoroastrianism and altered it to another religion. With that, the world changed forever.
