To address the second half of your comment, how do I explain “something apparently happening” when nothing ever happens? Many worlds might claim no definitive events occur, but it does claim that states become mutually dependent and interact, that’s all we need to perceive something occurring. What we perceive as events do not need to line up with “real” events outside our environment.

If you can emulate the universe on a computer, then you can also (with enough processing power) instead randomly generate universe states, either way you’ll eventually generate redbob, either way redbob exists, even if he’s just a pattern of numbers he doesn’t get to know that. Do events exist if the universe is just randomly generated numbers? Of course not, but redbob still thinks they do.

Given all that, events do not need to be “real”, they just need to look real from our perspective.

Edit: to be clear, not supporting nutty concepts like we’re in a simulation or a random number generator, just using them as thought experiments to prove that eventless systems can emulate the appearance of events and states internally
