This is a great thread, im really interested in Odin and his origins. I was looking into norse mythology and other northern Germanic pagan religions, and the origins
and relationships are very hard to determine to say the least. There is also much creidence to believe that many cultural figures in our modern day, are believed to stem from these religions. Another point that can back up some Norse figures, like Odin, were worshipped in european prehistory, is that the Germanic languages are believed to have a substrate that is non indo european, and many words and structures in germanic languages are non indo european. I theorize that the germanic pagan religions could also contain elements of pre indo european religions, just like the languages.
