Traditional eternalist arguments apply the relativity of simultaneity together with hyperplanes that connect spacelike separated events. For these arguments to work, one needs to assume both ontological simultaneity and the transitivity of reality. Consider three distant events, A, B and C. A and B are in fact simultaneous. B is in fact simultaneous with C. A and B are co-real, so are B and C. Therefore, A and C are co-real. All events exist tenselessly in spacetime. Whether something is past, present or future is dependent upon the perspective. Someone's 'now' can be some other's past or future: the past, the present and the future are equally real.
