"I would bump the origin of the universe to the top, because no matter what universe-generating physics you come up with I can always ask, "but what set things up to work that way?""

Except that it might not be possible to get outside of consciousness to have any testable way of explaining what set it up to be that way.

It seems that we are hard-limited by our consciousness, and have no way of going outside of it to peek at "the universe" beyond.
