I don't think I ever truly believed. The earliest memories I have are when I was 4. At that age I think I just believed what I was told without really seeing a need to question it. I remember around 6 or 7 I really started to question god. After all, I did find out I was lied to about Santa Clause. I remember questioning god but I was almost afraid to go too in depth in thought because of the fear of hell. I think I was just taking the 'just in case' route. After that I just kind of went along with it because everyone else did. Around 15 is when I really started to rationalize god and finally completely rejected the idea.
“You don't get to advertise all the good that your religion does without first scrupulously subtracting all the harm it does and considering seriously the question of whether some other religion, or no religion at all, does better. ”
