Yes, I get your point. We're all shaped by our environment. But that's ok, there's no "view from nowhere" that sets us ethically above everyone else. We do our best with what we're given.

But I disagree about Odin. I don't have to adopt the frame of the original adherents in order to evaluate claims of historicity. Odin wasn't a person (at least we have no evidence that he was). There is plenty of documentation about Jesus and the early Church (even if you reject their claims). Odin also doesn't solve any of the many philosophical problems that existence presents. He's just another version of infinite regress (although the idea of a personal god obviously has elements of truth compared with Christianity).
