Hmmm, invisible gods and invisible oxygen? Of course, oxygen is only transparent in the gaseous state - it's visible in the liquid and solid state.
But oxygen is of the physical universe, while the Christian god is of the metaphysical. Oxygen is obviously necessary for human life, the other??
Yes, if the atmosphere of the earth were to suddenly and inexplicably become oxygen-deficient for human life, the human species would indeed be in trouble. On the other hand, if invisible god(s) were found to be nonexistent, human life would be unaffected.
Therefore, it follows that we should continue to focus on the expansion of our knowledge of the
natural world and universe, of which elemental oxygen is just one small part of. Any time spent on the
supernatural, focused on the existence of a 'god' for which there is no evidence, is effectually,
a waste of the oxygen you're breathing. Thank-you for your assistance in making this point.
