Entity1: "The question of why is there 'something' rather than nothing
seems nonsensical to me. Even a vacuum contains somethings. Spacetime
itself can be said to count as a 'something'."
Entity2: "But why does spacetime exist in the first place? Why is there a
vacuum filled with fluctuations? Why is there even a universe, with
physical laws, in the first place? This is what we mean when we ask: 'Why
does anything exist at all?'"
Entity1: "Since there is no 'nothing' as you conceive of it, your question
is vacuous. There could not be a 'nothing'."

At this point the Simulators flip the switch and turn off the simulation
that is Entity1's entire universe. No more vacuum. No more fluctuations.
No more spacetime. Looks like Entity1 was wrong.

So let's ask again: Why does anything exist in the first place? If there
are vacuum fluctuations, why does there exist a spacetime and a set of
physical laws that cause vacuum fluctuations within it? Even perfectly
empty space would not be Nothing in the sense that is being discussed here.
  Nothingness is the absence even of space; the absence of all process and
computation.
