How can anyone believe in "logic" since it's invisible?

Interesting question! The atheist does not disbelieve in God because he has neutrally examined all the evidence, and drawn the proper conclusion that there is no God. On the contrary, the atheist radically misconstrues the plentiful evidence for God, and he does this because of his false worldview, which tells him that only the physical really exists. Before he has examined the evidence, the atheist thinks he knows that nothing non-physical actually exists, and this umption governs how he responds to the evidence. What's going on here? Does the atheist have superior insight that allows him to see the errors that invalidate the arguments for God that seem valid to us theists? Or is it the atheist who is missing something? I believe the latter ....
