Also, does this mean you do not believe your "Self" is real? Or that your consciousness is not real? How about your memories and experiences? Surely those must be real? Can you prove their reality by measuring them empirically?
Do you believe the laws of nature are real? They cannot be demonstrated, reproduced, or measured. They are explanations for the behavior of other, real, things. Anything which you call a law of nature can be reduced to the behavior of the things being observed without invoking some immaterial "law".
