If you have one or want to think up a few, here's an example on how this will go on:
Lets say in a hypothetical world the exists a God but no Scriptures are in existence, in this case this "God" would not be able to teach his teachings.
Now lets say there is a world where there exists Scriptures, but no God, this would not work either because of the simple fact of the falsehood of said scriptures.
Now to our world, If both of these things (God and Scripture) depends on the other in order for religion to be true, how can one proof the existence of one of these two things by using the other, because one of these two things cannot exist without the other. These two are actually one thing, so how can you prove this idea with proof of itself?
