In what age did you find out god does not exis?

[OnlyNatural]

I was about 20 when I stopped believing completely, after a couple of years of my faith slowly withering away, through a gradual process of questioning in my late teens. Becoming an atheist, I think, was inevitable, especially once I started university. Now my position on the supernatural is always one of disbelief, until I see compelling evidence to the contrary, and the more I live and learn, the more I realize that a naturalistic worldview is the only one that makes any sense.
