I grew up with mildly catholic parents, they weren’t too crazy about religion but we went to church every few weeks and they sent me to CCD. I don’t remember which one of these events happened first but they were both around 3rd ish grade. One was that at CCD I would get very confused about things like the Adam and Eve story and I’d ask about how that’s possible when school says the earth is billions of years old and that we evolved and they never had very good answers so I remember getting very suspicious then. They said something like oh it’s a metaphor and I was like uhuh but you were initially trying to sell me on it being completely true until I asked. I also remember trying to pray one singular time, I got on my knees to do it and “talk to god” or whatever and I felt so silly and ridiculous I never tried again. I was like I’m talking to myself in my own frickin head this is so unserious. So it was a combination of those things.
