Imagine viewing the world from state X at 1 pm, and viewing the world from state Y at 2 pm. State Y is required to be in existence in principle at the viewing of state Y, and at state X equally. This is because neither is more valid of a state to view the world from. Neither can claim it is more valid or true at their own unique particular locations, as we must apply the identical logic to the other location that is not observed at that particular time. So, physically only state X exists when I am viewing the world from state X, but in principle, state Y must fully exist as well, while viewing the world from state X. Therefore, if we extrapolate this to the larger world, and all times and locations, then in principle, all states are equally existing at all times. The future is an illusion, as it is a logically valid and completely physical present state in principle, regardless of where I view the world from. Objectively, the location from where I observe the world is irrelevant.
