You’re still confusing a simulation of a specific event with a simulation of a universe. If you’re simulating a boat in the water, you need the water but you don’t need to build an entire ocean with fish and land near the water and buildings on the land. You just build what you need to simulate. We are clearly in a much larger simulation than one that would simulate an event.
If you don’t know what they’re testing that could certainly seem excessive. But failure of imagination doesn’t prove it’s impossible, although you can argue it’s unlikely
