Abstract
From a geometric perspective, we proved the following conclusions, that are against mainstream scholars’ viewpoint. (i) Vanishing of the covariant divergence of matter energy­ momentum flux density in entire spacetime is a conservation law of matter energy-momentum. It reads the net increase of matter energy-momentum in any infinitesimal neighborhood of spacetime is zero. Hence, introducing gravitational energy-momentum does not save, but destroys the law of energy-momentum conservation. (ii) Interaction or force in physics always means exchange of energy-momentum. The spacetime metric field (gravitational field in general relativity) does not exchange energy-momentum with all mass points and matter fields. Therefore, the metric field of spacetime does not carry energy-momentum, it's not a force field, and gravity is not a natural force. The spacetime metric field is the geometrical aspect of moving matter 4-dimensional continuum. It is not a matter field itself.

Keywords
