Did you read the first reply? Because the first reply already explains it completely.
Look up the cybernetic principle if you want it in mathematical and complicated, or look at emulation technologies to understand the technical perspective. The fundamental structure of reality demands that you conscious mind is smaller than your subconscious mind, and your subconscious mind is smaller than your foot print in local society and so on. No entity or system can conceive of anything more complex than itself, which is why you can never perceive reality, only the slice of reality that fits into the part of what you can keep in mind of what you know about reality. Biological life is a simulation on top of chemistry, which is a simulation on top of nuclear physics, which is a simulation on top the standard model or string theory or quantum chromodynamics or maybe it's all just Tarot and piss.
That's why
>are we in a simulation
is not a useful question, because treating it as a simulation has us searching for secret cheat codes, instead of doing proper research that can be useful for everyone, like for example AI assistants that give you SCP psychosis.
