Where did Odin come from?

[Okay, maybe Mike Johnson is a competent parliamentarian.]

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.
