Motion in our universe comes from the four fundamental forces and space/time expansion. No supernatural explination required.
The existance of energy is proof that energy exists. It is NOT proof that something exists outside of space and time. And it's NOT proof of any kind of creative agency.
"I don't know how this works - therefore God." Is not a sound logical argument. You cannot solve one mystery with another mystery. You cannot explain one unknown by postulating the existance of another unknown.
