Do any of us really know anything?

there is an infinite universe, but there is not an infinite combination of atoms, so somewhere out there, there is an exact copy of you living in an exact copy of your town on an exact copy of earth in an exact copy of the solar system in an exact copy of the milky way galaxy...

that's what I'm like to. What if no-one exists, what if no-one is here, and this is all in God's mind, who's forever in Acoma.
