Just as likely an outcome as any.
I read a great novella about a guy who was a devout Mormon who got sent to a truly chilling version of Hell because “I’m sorry, the correct answer was Zoroastrianism.”
Never heard of it before, but it seems to have been a major source for inspiration of Judaism, and from that of course Christianity and Islam.
So since Zoroastrianism seems to have been the original monotheistic faith of the 4, it makes sense that the copies of the original are the fake ones. Except of course they are all fake, and none of them make the least bit of sense.And zoroastrianism split off/evolved from the old proto-Avestan traditions, which themselves evolved alongside/from an ancient Indo-iranian root, of which Hinduism is the only other surviving branch.
Ten holy hecks, all major religions are cousins.
