When, Where, How and Why did you become Atheist?

[Mister Agenda]

I've noticed that people around d the 12 thirteen mark become Atheist. Maybe it's the hormones and atheism is one giant hormonal rage? jk

If it was hormones, I was very late (mid-thirties). If it were hormones, wouldn't they have a tendency to revert back once the hormone tide receded?

If you are correct in your estimate of when it usually happens, childhood development might be the better explanation. When we become old enough to question what we've been told by our elders, what we've been told doesn't always stand up to the scrutiny. There's a reason religious indoctrination is begun before we have any skepticism to defend against it.
