And the evidence for it does exist... unless you're a materialist pseudo-skeptic...
Yes, Earth is a Simulation, like a Holo-Deck, etc.
It doesn't matter. What's happening is real, even inside a holo deck.
> What's happening is real
Only because of that «blasphemous» C-word...: Consciousness
It's only real to your mind because you observe it, yes, it seems real in the materium. But as for reality, it's not and it can be proved, as you observed it and create it, it's real to you and your mind.
It would make sense to me that reality is ultimately a data stream. It does not make things meaningless but rather the division of thought and matter to be opaque. And evidence does seem to point there.
It does not immediately signify omnipotence. But it does signify perhaps "pseudopotence" - we sort of control anything... but in ambience, with unclear limits.
No ISBE can have omnipotence, because all ISBEs have the same rights.
The limits are very clear. If you need violence to get what you want, it's because you are violating the right of another.
