I tried so hard to hear God. When I finally talked to my pastor about my doubts he said that reading the Bible would help. Reading the Bible made me doubt even more.
Wasn't raised Christian, but had a similar experience. But I definitely believed in God, heaven, etc, because they seemed like facts of life. I just thought there must be more to it.
Anyway, precisely because I took these metaphysics seriously and at face value, and because I wanted to know more, I kept digging. And as any seeker of truth knows: if you keep digging at a lie, you will reach the bottom in short order.
I only had to wait long enough for my youthful incredulousness to fall away. What a waste of time... I couldn't been studying music theory or something...
I clearly remember the moment when I realized that other people (other than weird fundies) were taking it seriously. I'm not sure what I had thought was going on, my best guess is that I thought praying and going to church was just a weird thing we were all supposed to do out of politeness, like not putting our elbows on the table.
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
