5 to 20 -- unquestioning Christian (BS detector was fried early and well).
21 to 35 -- resisting cognitive dissonance
35 -- the dam breaks
36 -- 38 looking for alternatives and not finding them
39 -- 42 admitting to myself that I didn't believe, and figuring out what I DID believe
43 -- 48 closeted atheist
49 -- 62 (present) self-labeled atheist and happy with it

• < 5: born and reared into a conservative Catholic family
• 5–10: attended Catholic parochial school, nuns and all, questioned articles of faith, was told "mysterious ways," accepted "one true religion," felt special
• 8–17: altar server (and the answer is "no" )
• 11–17: attended public Jr.-Sr. high school, felt morally superior to everyone else
• 18: started studies at strict Catholic college, still convinced of Catholic tenets, arrogant prick
• 18–20: learned church history, theology, etc., discovered that the religious "truths" were often majority rule by committee, disagreed with Catholic ethical reasoning, started questioning Catholicism and Christianity, started paying more attention to philosophy and other views
• 21: college closed, attended another college (more secular), more interested in philosophy, took course in the problems of philosophy, heavy focus on religious concepts, e.g., God and the soul and immortality and the logical problems these concepts face, still believed in some nebulous form of God
• 22–23: went through agnostic phase, emerged a negative atheist, not open with most people
• 24–26: felt betrayed by family, clergy, and community for lies and indoctrination, certain they should have known better, still attended church to appease family
• 27+: started to realize that even highly intelligent people have blind spots and are often themselves subject to the effects of indoctrination and the hope in things that faith promises, let go of my anger and hurt, stopped attending church, open and honest about my views but don't go out of my way to discuss religion unless asked

Glad you climbed out of that cult one rung of the ladder you describe each per Piaget observation

I never really bought into religion (I hated having to get dressed up to go to church), I noticed the difference in the behaviors of my classmates in church, and at school (elementary age).
I married a catholic and was married in the Catholic Church, but never joined. We were in a folk music group in one church. I enjoyed some of the messages of love and caring for your neighbors, but still never accepted any of the Christian dogma.
I never really considered if I were an atheist or not, I just couldn’t rationally accept the majority of the Bible.

From altar boy to altered veiw. Hypocrites in high places preaching one thing and living another played a big part.

Belief in Bible as illustrative myth: Raised in Disciples of Christ church. No literalism. Jesus as a love message. Fairly sheltered faith with almost zero ugliness. Golden Rule christianity. I generally believed in a non participative but benevolent god. Never believed in a devil if god was omnipotent. Baptized into my childhood church at age 12, along with an entire class of other 12 YO. (ages 5-18)

The big turn off, "Real church/christianity": From college years forward, witnessed "christians" as haters, bullies, bigots - agst gays, atheists, other christians, everyone. Understanding religion to be a human construct, seeing it weaponized to justify any hateful/selfish belief, turned me off to church. Considered this a human failing. Still loosely held on to a personal god concept, though questioned how such a deity could allow such abuses. Took our kids to a few churches to teach them about religion, not indoctrinating them. Husband and daughter got baptized. Husband died of cancer in 2006. Attended unprogrammed (no sermons or dictated belief) Quaker meeting for three years. (ages 18-44)

Books grant me permission to question ALL of it: My dad, who was very well read in world religions and secularism, gifted me with books by John Spong and Neal Walsh. ("A New Christianity for a New World" and "A Friendship with God" ). These books seemed to grant me permission to critically evaluate religion, including mine, and to consider discarding religion altogether. Ultimately brought me to where I am now: non-religious, nontheistic. I don't believe in a god being, figuring "god" is how many humans explain what they do not know. (ages 44-46)

My "fuck religion" phase: early in my no-longer-believing years, I read and discussed a lot, shooting as many holes in religion, and especially christianity as I could. I was pretty angry at the many wrongs religion has dished out and felt a need to rail about it. I shudder to think how anger-constipated I might have been had I actually experienced a more authoritative/abusive brand of christianity personally. (ages 47-52)

Present: I tired of being angry and of rehashing the same anti-religious arguments over and over. I understand the need to vent such sentiment, especially for the newly disbelieving. I personally want to move past that and enjoy a more peaceful and satisfying life as a humanist, with reverence for all life and the environment.

I read and reread the Bible starting from when I was eight years old, so was aware that the Hebrew god was misogynistic, cruel, revengeful, arbitrary. But my dad was the same way, yet was considered a "wonderful Christian missionary," so I accepted our deity being equally messed up.

I thought anything that happened that was "supernatural" was "god"answering my prayers, but eventually I realized that I got EVERYTHING I wanted, or decided to have - good or bad- so things that happened had nothing to do with "god" and religion. I was the only one making things happen, so was in fact "god."

Also I read the Sumerian texts, carved in stone 2000 years before the Bible was written, so I knew the Bible god behavior and personalrity was based on "Anu," the blood-drinking Sumerian alien god.

But the racist, bigoted, misogynistic memes and behavior of the white evangelicals during the 2016 election is what pushed me to toss everything to do with religion.

Pretty similar timeline for me, if just a few years behind. I thought 5 years old was pretty early/advanced (in a backwards ass way) to be able to claim you understand and accept Christianity. I was probably pretty devout and unquestioning from 5-12* (inwardly a few questions would always pop up but none that met the light).

Questioning others’ Christianity, and Christianity’s claims about gods nature but not god from 12-17

Studying the hippie movement, war atrocities, eastern cosmologies and comparative religion from 15-21 led me to form my own philosophies.

Being “spiritual but not religious,” sort of aimless and dabbling in high functioning alcoholism and existential dread from 21-27

Admitting that I’m an atheist and antitheist and taking more control and responsibility for my own problems 28-present

Hard to say have questioned things a long time
