Yeah, that's my thought exactly. If we are in a simulation, I think human beings are specifically what's being studied, so it's unlikely the simulation would have actually run through millions of years of evolution. If that is the case, it could have begun at any time. Even at some point in modern history. Hell, yesterday, for all we know. Of course, this is all speculation. There are endless possibilities and we may never know for sure what the truth is. There could be obvious tells right in front of us that we've been programmed to completely ignore.
