You have not settled the question by bringing forward a theory according to which there is nothing to be observed, and by then reiterating that nevertheless we do observe this non-existent fact.
Unless motion is something as a fact in nature, kinetic energy and momentum and all that depends on these physical concepts evaporate from our list of physical realities.

Even in this revolutionary age my conservatism resolutely opposes the identification of momentum and moonshine.
Accordingly I assume it as an axiom, that motion is a physical fact.

It is something that we perceive as in nature.

Motion presupposes rest.
Until theory arose to vitiate immediate intuition, that is to say to vitiate the uncriticised judgments which immediately arise from sense-awareness, no one doubted that in motion you leave behind that which is at rest.
