The reason I don’t accept that the Universe is a simulation is closely related to the reason I don’t believe it is the work of a supernatural intelligence. The demonstration of quantum entanglement and its proof that the observed behavior can not be attributed to “hidden variables” means that any simulation would need to be able to transmit information faster than the speed of light. Since the simulation would also be subject to this limit it would be impossible to simulate. The other part of the argument is that quantum behavior like radioactive decay is truly random in time unlike any other deterministic behavior like coin tossing whose randomness is really just due to our ignorance of all the forces and initial conditions that preceded the observation of heads or tails. God would of course know whether the coin would come up heads or tails but even He could never know when a neutron would decay in a radioactive material. If there is information in the system that is beyond even God then He can’t be the supreme being and the creator of everything. There would have to be higher laws or principles that even He was subject to.
The simulated persons users interact with continue to operate within the simulation whether there is a user present or not which isn't really in keeping with the view proponents of a simulated universe espouse.
Thing is, Dave, He does know (even the decay of a radioactive particle), and He exists outside of the Creation He spoke into existence, while His Spirit and Son are active inside of it. See how easy that is?
We either can by faith accept that He is and that He has a purpose for each of us, or that we are all random and w/o purpose and therefore worthless.
One path leads to life and pursuit of excellence until we pass from this life into eternity with Him; the other, just a free for all until the darkness arrives, and we wake up in the presence of the LORD GOD Almighty and gulp.
