Improbable is meaningless with the anthropic principle. The set of MWI
universes with Gods would have the same physics and statistics as the
rest of the MWI universes, but within these MWIGs the UMs which the
Gods have learned to build and program would have the physics of the
Gods' choosing since the UMs are actually living in a nested virtual
universe.

What you suggest in saying that no event can be known to be
supernatural is the same as saying that all video games would have to
have the same basic rules. It's an arbitrary deus ex machina to plug
the hole in the two theories, which, if both were true, clearly make
the certain epistemology of primitive physics in any universe by it's
inhabitants inaccessible.

The only way out of it that I can see is to acknowledge that it is
possible for 'sense' to transcend logic and therefore at least
indirectly access a level of primitive truth through physics, which is
exactly what multisense realism predicts. This corresponds to our
ordinary experience of implicit 'seems like' epistemology which makes
our perceptions specular participation in a real human world rather
than a solipsistic simulation.

Yes, but I'm saying that through comp, we cannot know that we are in a
universe at all. We could be programs in someone else's universe, and
our arithmetic and logic the meaningless hallucinations of a brain
simulation that makes us feel our logic makes sense by stimulating the
corresponding regions of our brains with the appropriate virtual
chemistry.

In a comp simulation, there is no truth, only internal consistency,
which could be easily simulated by disabling the ability to detect
continuity errors.
