If we are living in a simulation, it is a simulation of atoms, or quantum fields, or perhaps something deeper behind that. That got started with enormous energy in the form of hot dense quark gluon plasma. From there the rest follows. It is not a simulation of humans. We have zero indication there are rules at a higher level than the quantum or gravity. Like rules on what you ought to do in the bedroom. Also earth no…
You're taking some mighty large liberties defining what our simulation is, and how it started. A simulation can begin with any state, including a hundred years ago with already written books and simulated Big Bang background radiation. There is no difference.
Especially when such ideas are grounded in bronze age thinking.
"There is no difference." Indeed, if god exists or not, there is no difference ...
