Ah, telling a rocket scientist he is incapable of logical reasoning. Very good.
Have it your way. Eyewitness accounts respected, collected, preserved and distributed by thousands of their contemporaries don't count as evidence.
It is true that those eyewitnesses did testify that "all Scripture is inspired by God" and therefore, if you choose to believe them you can proceed to infer that God wrote the Bible. But it is not required that you believe that until you decide what to do about those pesky eyewitness accounts.
