That leads into my thinking of why it frankly doesn't matter whether god exists or not. Either way, we would be unable to know one way or the other, and hence concerning ourselves with the question is inherently wasted effort.
It's like asking what is behind the edge of the universe. It does not matter. By definition we cannot perceive or interact with it, as the very concepts that make up our space of perception and interaction terminate at the edge. Likewise if there did exist a higher metaphysical entity, by definition it would exist outside of our sphere of perception and interaction, and hence it is exactly the same for us whether it does exist or not.
