That is a good pushback! But isn’t Presentism also an interpretation placed over the top? To keep a river of time flowing and cling to an unwritten future in the face of relativity, Presentism has to invent a hypothetical, unmeasurable privileged frame of "Now" that no experiment or GPS satellite can ever detect. The Block Universe simply accepts the 4D math as it is written. Presentism seems to avoid the basic physics by inventing an invisible mechanism just to keep the present moment special. I personally abandoned Presentism because of Occam's Razor. Why invent an unmeasurable hidden frame just to preserve an old idea, when the 4D block explains the physics cleanly without adding extra entities?
