Where did Odin come from?

[🐒Gods of Prosperity🔱🐲💸]

People have been suggesting since the 1870s that Odin is a later addition to the Germanic pantheon. The late-Victorian view was that original supreme god was Thor, who of course is a thunder god, and that Odin was parachuted in later as part of some broader social shift. I'm not sure if that's still the received understanding now, though.

Or maybe the development of different aspects to the deity, and eventually becoming distinct personalities?  That sort of thing happens sometimes.
