When I reply to people who use the "god gap" fallacy I say this:
What's the square root of 727?
Unless they are some kind of math whiz, they won't know. To which I reply "Then the answer is seven, since seven is the divine number of God in the KJB."
When they protest that they can get a calculator or figure it out, I reply with this statement:
"What if you didn't have a calculator or didn't know how to figure out square roots or didn't understand that kind of math? By the same logic you are using, the answer has to be some form of God so therefore: seven. And the answer to any math problem you don't have any idea on how to figure out will always be seven, no matter what.
"So therefore, since you know all the answers, there's no real reason to learn."
....That usually stops these conversations.
