According to Everett's theory human intelligences are "complex internal processes" in Hilbert space*. (The Emergent Multiverse, D. Wallace, OUP, 2014, pg 100 ) Could god simply be an even bigger (or even an infinite) "complex internal process" in Hilbert space? And possibly entangled with our world? To believe in such an extraordinary idea would, of course, require extraordinary evidence. Its just a thought.
