About Relativity Theories: only a conscious observer can experience events moment by moment in the present moment

Only conscious observers can experience the unfolding of events moment by moment. Establishing a reference zero point requires privileging an actual present moment, something that inanimate matter within the four-dimensional continuum is, in principle, incapable of doing. Because an inanimate object merely forms a static worldline with no preference for any particular spacetime point, the true origin of a reference frame can never be a material particle. Only a conscious observer can: an animal, a human being.
