Time is just another measurement humans put on something in order to try to understand it. It marks change nothing else. That's all we do is change. Look at each decade. Each decade we shift into something new. Our lives continuously changing by the choices we make. Life becomes better bit by bit the more we choose better. Our evolution is blatant when you can see it. If all is eternal how is time ever relevant? Energy is information. Information is never lost only rearrange.
