New Idea for Sims 4

You have to keep in mind that The Sims doesn't aim to be an exact simulation of our reality; it only incorporates aspects that make the game more interesting. The Sims takes place in a fantastical universe where magic, genies, fairies, vampires, werewolves, aliens, the Grim Reaper, ghosts, reincarnation, superheroes, cloning, and time travel are confirmed to exist. Naturally, I would expect religion to exist as a concept since it's a very human thing, and Sims are, after all, humans. However, none of the real-world religions would make sense in that context.
