I agree with VIBE. Sure, the similarities between Santa and Yahweh are clear to anyone who's willing to look at it objectively, the differences are far more significant. Santa, and those like him are something fun to believe in during certain celebrations or events. Yahweh, on the other hand, serves as an explanation for existential purpose; as the very reason for being for roughly half of the world's population. Because of the significance that is placed on believing in Yahweh, you can't equate it to believing in Santa or the Easter Bunny even if logic would suggest otherwise.
