We can exclude that possibility because it’s a possibility that we can’t observe by any means. If what you’re suggesting is true, that a higher being is interfering and modifying our reality, then we should be able to test that assumption. Anything that can have a physical effect in our world is testable in our world. Since we don’t observe that happening, and according to you can’t observe it since doing so would end the simulation, it’s a possibility we don’t have to consider because it’s impossible to prove it or test it or, most importantly, to falsify it.
Again, it’s the exact same argument as the one day old suggestion. It’s ultimately meaningless.
