What is it rhen aside from chemistry and physics?
Do you understand what it means to falsify the contrary?
That might seem like an odd, even esoteric question, but it is a real question that you really do need to answer, for yourself if not for any other reason.
If only A or B is true and A is falsified then B is necessarily true.
Can you not see that?
The supernatural is either real or it is not. Put another way, either "supernaturalism" is true or naturalism is true. It cannot be both, nor can it be neither. The two are mutually exclusive. It IS one or it IS the other. Thus, if naturalism is falsified, which has been demonstrated here without even any attempted refutation, then the supernatural exists and your worldview is falsified.
More specifically, and in direct relation to this latest exchange, if logic and reason cannot be the product of naturalism then it must have a super-natural source. There is no other alternative. That which is not natural is super-natural, by definition.
Thus, the direct answer to the question, "What is it (i.e. logic and reason) then aside from chemistry and physics?" is...
"Logic and reason are not merely the products of chemistry and physics, because they deal with the validity of thoughts—not just the occurrence of thoughts. Chemical reactions may explain why a thought happens in the brain, but they cannot account for whether that thought is true. Logic is the ground by which we distinguish valid inference from invalid, and reason is our capacity to recognize and follow that ground.
If all our thoughts were simply the result of material processes—blind physical causes—then we would have no reason to trust them as accurate or truthful. The act of reasoning requires that we step outside the flow of physical causation and evaluate arguments on the basis of their logical connection, not just their natural history.
Therefore, logic and reason are something more than physics and chemistry; they belong to the realm of the rational, not merely the physical. If Naturalism were true, it would undermine the very reasoning by which it is believed." - C.S. Lewis - Miracles chapter 3
You might respond, "Logic and reason are something more than physics and chemistry? Something more, like what?"
Indeed, that may well already be what it is you're asking, but if so, then I would respond by saying that you already know my answer! You know, but won't admit to yourself, that I not only have an answer but that my answer makes sense; that my answer is rationally consistent with the whole of my worldview.
But that isn't your line of thought! Your line of thought is that there is no answer and you're projecting! You have no answer and think that I (we) don't either!
The answer to your question is that our reasoning faculty; our ability to think, to know, to understand, and to distinguish truth from error, is the part of us that was created in the image of THE Logos (i.e. God!).
What's more is that this isn't just my answer, it is THE answer; the
only possible answer. It MUST be true, just as surely as 2 + 2 must equal 4. It cannot be otherwise and as such, you are without excuse because the truth has been shown to you. (Romans 1:20-21)
