Because just read that sentence again: “Energy cannot be created nor destroyed”...That means “Energy is infinite” What else could it mean? It means it has no beginning nor end, it is infinite. And if it is infinite, then time has no bearing on what happens to it. Time is out of the equation. Whether it’s a billion years from now, a trillion, 50 google years from now, eventually it will form into mass, atoms, molecules that form exactly into the same cells, neurons, memories that make you what you are right now. What I am saying, is that if energy is infinite then this is proof of God. It does not mean that God is an old man in the sky programming the universe like a computer programmer, but an infinite being that is energy where time has no bearing but does in fact exist. Everything that exists is God. I always use to laugh when Davey use to say on that show “Davey and Goliath” “God is everywhere”..He was so right.
It could mean that energy is finite. There won't be any more energy even though there won't be any less.
