Scientific method is the process. Science itself includes the study and compendium of understandings, based on a belief system that includes shared understandings just like mathematics. The foundation of these are philosophical beliefs that we can know and understand these things. For example, on a metaphysical level, if the world around us were a simulation, then science could provide understandings about that simulated universe, but not about that which is simulating it.
This I'm afraid is rubbish. Scientific proofs categorically don't depend on philosophical beliefs. Reality is measurable and the properties measured don't care about philosophy.
