Sorry Stat, it's not rational whatsoever. Nothing stops Muslims from using the same argument that intelligible thought is impossible without presupposing Allah is the source of all existence. This presupposition argument reeks of desperation and special pleading for the Christian God. I could come up with an infinite different definitions of god that would all be valid under presupposition apologetics by presupposing my definition to be true. It boils down to the fact that the bible cannot be proven to be true, so it must be assumed to be true to prove the Christian point of view.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
