How can eternity have motion without a first case?

Even in physics motion is caused by a loss of potential energy. So eventually all motion would cease once it reaches minimum energy and is in equilibrium, even in a system as large as a uni/multiverse.

Energy is always conserved. Kinetic Energy + Potential Energy = Total Energy. Thus if KE is at a minimum PE is at a maximum.

What is heat? How can a system move forever unless something external to it supplies energy?

motion is caused by a loss of potential energy

All energy has the potential to be any other type of energy, thus all energy can be thought of as potential energy. Even mass is just potential energy. Thus our whole universe is energy, and as far as I can tell it does not need a first cause just as your first cause does not need a first cause.

Motion and the themodynamics sure do. An eternal universe would die a heat death, and because every motion requires another, the universe requires an uncaused cause in it's beginning. All motion is caused by minimization of potential energy and converted into kinetic energy and more specifically as heat/waste. It cannot go backwards. That is, if the universe is eternal, something outside it supplies energy.

But science, math and philosophy don't matter to you. You are determined to not believe in a God despite critical thinking. The reason God is an uncaused is because He never had a beginning.

Your argument is the heat death of the universe implies the universe had a beginning?
