How did come to be a believer or non-believer?

[Warren Stupidity]

8. raised by agnostic/atheist parents who encouraged me to think for myself.

so I did, and it was clear that the iron age christian mythology was about as real as the bronze age greco-roman mythology it replaced, that we emerged from 1000 years of intellectual stagnation as a civilization around 500 years ago, and that in doing so we reconnected with the incredibly rich philosophical traditions of the stoics and epicureans and others that rejected irrationalism and religiousity, that embraced skepticism and humanism, and that the enlightenment, the renaissance, is still very much a work in progress with no guarantee of success, and that we all need to choose sides.
