Religion is another way of knowing
The first question to raise is "Knowing what?". according to the biblical knowledge - not much... a few things claimed to be known by the bible include: Pi is 3, The earth is flat, The earth is "held up" and talking snakes use to do more than just slither.
This argument is claiming the god of the gaps argument is true, and that they know that it is true. The argument is a God of the gaps argument because they say that god did everything, and they know it. This is odd as it is commonly raised that you can't know everything by both sides.
