But Judaism and Christianity didn’t originate in Arabia, but other parts of the Middle East. They were influenced by stories from the Sumerians (and Egyptians) whose civilization dates back to 5-6000 BC. Gilgamesh and the flood myth are far older than Abrahamic religions. And archeology shows us that humans all originated out of Africa.
Thus, my point is that the reason that all prophets are from the Middle East is stories can only travel so far. This is why a Native American would have never heard of any Biblical stories had it not been for the discovery of America. We have to consider the possibility that religions may be man made. This does not disprove the existence of a God, it just questions the authenticity and purpose of scriptures, prophets, and rituals.
It’s not up to me to define someone’s beliefs, but I do have questions because, if one considers religion to be the word of God, then there are many logical inconsistencies.
