The best argument I've heard against the simulated universe is that you would need the energy of an entire universe to simulate a universe. But then again, there are already some games that simulate the entire galaxy, like No Man's Sky, although, I guess, not very precise. We haven't even come to a point where we can precisely simulate an Earth-like planet. GTA games come relatively close to simulating a city.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
