I had a crazy idea for an alternate time line in which the Ancient Persian philosopher Zoroaster; instead of being the founder of the religon of Zoroastrianism, was instead the prophet in Friedrich Nietzsche seminal work Thus Spoke Zarathustra. In addition, in this time line Zoroaster is not a Persian, but a Greek (in keeping with Nietzsche love of Ancient Greece). In this time line Zoroastrianism is not the religion it is in our time line, but a philosophy or school of philosophy in ancient Greece, probably starting at the time of Homer or shortly after. Is this even remotely plausible? Am I staying up way to late at night?
