Very well put, we as humans are very limited in what we can comprehend and understand of the universe. Still, I don't think we should be too eager to reach for the easy way out - being the god theory. Just because we can't explain it now doesn't mean we never will.
I would disagree. I would say that we, as denizens of a dirt ball far out on a spiral arm, are very limited in what we can directly measure and observe. There are no barriers to comprehension. I am a fundamentally faithless individual. I do not see God in the gaps. That said, if I were a spiritual person I'd be more inclined to see "an invisible hand" in the stuff that can't be easily derived than in the stuff we only know about because we derived it.Very well put, we as humans are very limited in what we can comprehend and understand of the universe.
