He eschews what many scientists refer to as creation out of nothing, because of the religious connotations. To accept the idea of a beginning in time therefore means that the conceptual foundation of time, i.e., matter, also had a beginning. One could state that matter always existed but motion did not. Yet, the idea of matter without motion is absurd and without all precedence.
Motion is the mode of existence of matter.
Never anywhere has there been matter without motion, nor can there be. Matter without motion is just as inconceivable as motion without matter. Motion is therefore as uncreatable and indestructable as matter itself. It just cannot have any cause at all in the universe of the given model, nor, of course, can that paramount occurrence be the effect of any prior cause. It cannot be a scientific assumption.
