Even believers must admit that God is essentially mysterious; if there was a creator who wanted its presence known unambiguously, then it wouldn't be a frequent point of contention.

Rather, I think this an issue with the human psyche, which is complex, but unambiguously real. Whether or not there's a God, there are many who clearly want to believe in something which is omni-present, and I'm guessing that for those with no faith, or for whom their faith doesn't scratch that itch, they fill that gap with a fictional Good Guy Government that protects you while you sleep.
