I agree. As a metaphysical ponderer, I often consider how "illusion" is fundamental to our understanding of science. Consider this: all physical laws and theories are verified through human experience on a time scale, ie: under these conditions, you will observe this result. There is always an observer and at least two points in time. Time, and observation of it, is the ground truth of all physical laws, of our very experience of the universe.
Even in your mathematical derivations, there is an implied observer and time line. Ie: "Using these axioms, performing these operations, you will observe this result". (Precondition, action, result)
