Odin was a wanderer; he sought knowledge. He's not a creator.
But Odin according to the mythology created mankind from sticks he found on a beach leading to his name of “Allfather” so he definitely is the creator deity of Norse/Germanic mythology. Which again is weird that unlike practically every other creator deity he has no association with the sky, sun, or thunder. Also you brought up another point I wanted to touch on which is how weirdly contradicting Odin is. One hand he is depicted either as a war god all dressed up in armor or on the other hand as an old wanderer. It is such a weird clash of ideas and combined with lack of similarity to other creator deities it really is fascinating to think of why the Germanic and Norse people developed him as such
I should have said Creator rather than creator; I agree it's clear he crafted but isn't fully the 'creator of everything' in the traditional foundation sense.
