I had the same thing when I was younger! In my head, it was like a thing people do just for tradition(or something?) that everyone knows isn’t real, but we play along for fun. Like when you knock on wood or wish on a star. Or when adults talk about what “Santa” brought them (and I don’t mean the people that genuinely believe in that shit). I dunno I had the concept well developed in my head like it was all some sort of metaphor and then my mind was blown when I learnt people actually think jesus was a real life wizard
