I don't think I can describe my becoming an atheist as a choice exactly. The reason that I became an atheist is because I couldn't find any evidence for the existence of any gods that I knew of, and I was not in the mindset that there has to be a creator. Once I realised that there was no evidence in front of me that a god exists, it made me question the various notions of religion, which up until then I had accepted as historical fact.
If you believe it, question it. If you question it, get an answer. If you have an answer, does that answer satisfy reality? Does it satisfy you? Probably not. For no one else will agree with you, not really.
