Herein the simple analysis of the basic transformation equations reveals that the idea of motion transformations is the foundation of the laws of nature and such that the idea of the arbitrary space-time transformations is in fact only an excursion. Herein it is emphasized that the mass and energy variables are substituted into the equations, instead of the space and time variables, precisely because what is fundamentally and appropriately considered in physics is purely the motion transformation and its result. And herein presented are the kinematical formula for the creation process due to gravity and the kinematical origin of gravity.
