Wrong again. You don't seem to know what a logical proof entails. But if you insist that circular arguments can be valid, then any Muslim can prove their worldview using the same form of argument. TAG works for Islam as well as Christianity if circular arguments are proofs. Maybe you are borrowing capital from the Islamic worldview??
You don't know what skepticism entails either. A skeptic will refrain from making truth claims. Often they are known as radical empiricists. I have no problem making truth claims, I prove truths from the axiom of Scripture. I even claim Scripture is true although it can not be proven since it is the starting point of my epistemology.
The problem you are having is you think you can take your particular worldview and prove it is true - but since the axiom defines the worldview, it can not be proven. That's presuppositionalism. You are going to have to refute presuppositionalism or the necessity of axioms. But since proofs presume axioms, and nothing that is presumed can be then proven, you can do it logically. A proof is not valid if the conclusion is presumed. Again, this is Logic 101. You can try to run, but you can't hide.
