My impression was that baftan was raising the issue of freedom/creativity in thoughts, something which seemed less clearly present in DNA, molecules, even neural structures. Further humans have come up with formulas in pure math that often after these humans died turned out to represent actual relationships 'out there'. Baftan, I think, raised the issue of formulas not because he was confused about how they related to external reality, but rather raising the issue of how brains/neurons can come up with things that are new, never before thought of, and, in many cases true. I am adding in the issue of formulas that turn out not simply to be elegant and of interest only to mathematicians - some of whom even would have preferred the formulas had no use - some pure math guys and gals actually like math for math's sake - but then these very formulas turn out to be useful in describing natural phenomena. How do brains come up with such things?
