What if earth is the universe as we know it. And we are living in the afterlife, the afterlife of various stars and collisions and entanglements.

"You take yourself with you wherever you go"

We were all once partially made of star material at some point in the past, so could it be said living bodies are dead stars?

Perhaps we only reincarnate as long as it takes to form our own galaxy of stars. one galaxy or star for every human life.
