Lol, only my nickname is Greek.
Mythology implies constant intercultural borrowing. Mithra comes from Persia. Some of the Greek orphic myths may well have borrowed from Levantine (Canaanite/Phoenician/Israelite) mythology too, cf. http://www.jehovahs-witness.com/10/68224/1.ashx.
Along with awareness of intercultural influences the realisation may come that the quest for any "true origin" is not the least of myths. Which in turns makes every myth, including the latter one, interesting on its own merits.
what is your conclusion on god , the universe and everything
