Causes of atheism
There are a number of reasonable explanations for the causes of atheism:
1. Moral depravity: The history of the atheist community and various studies concerning the atheist community point to moral depravity being a causal factor for atheism. In addition, there is the historical matter of deceit being used in a major way to propagate atheism from the time of Charles Darwin onward. Also, Bible exegesis points to the moral depravity of atheists. Moral depravity is certainly one of the prime causes of atheism. Francis Thompson wrote: "Maybe the atheist cannot find God for the same reason a thief cannot find a policeman." (see also: Atheism and morality )
3. Atheistic upbringing. However, according to recent research by the Pew Forum on Religion and Public Life, in the United States, a majority of those surveyed who were raised in atheist or agnostic households, or where there was no specific religious attachment, later chose to join a religious faith. A notable example, of a person raised in a atheistic household who later became a Christian is William J. Murray. Mr. Murray was raised by Madalyn Murray O'Hair who founded the organization American Atheists. In addition, Christianity is experiencing rapid growth in atheistic communist China and has experienced rapid growth in former communist countries. 
4. Rebellion: Atheism stems from a deliberate choice to ignore the reality of God's existence  Dinesh D'Souza declared: "Look at Satan's reason for rebelling against God. It's not that he doesn't recognize that God is greater than he is. He does. It's just that he doesn't want to play by anybody else's rules. This idea that it is better to reign in hell than to serve in heaven is Satan's motto, and it turns out that this is also the motto of contemporary atheists such as Christopher Hitchens." 
6. Naiveté/Gullibility: Many atheists have embraced a number of far fetched, unworkable, and errant notions and ideologies such as communism, abiogenesis, and evolution despite abundant evidence of their falsity. See also: Causes of evolutionary belief
7. Irrational thinking: As noted earlier, a comprehensive study by Baylor University found that the irreligious and the members of more liberal Protestant denominations, tend to be much more likely to believe in the paranormal and in pseudoscience than evangelical Christians. Also, as noted above, a 1980 study published in the magazine Skeptical Inquirer found irreligious college students to be by far the most likely to embrace paranormal beliefs, while born again Christian college students were found to be the least likely.
8. Superficiality: Noted ex-atheist and psychologist Dr. Paul Vitz has stated that he had superficial reasons for becoming an atheist such as the desire to be accepted by his Stanford University professors who were united in disbelief regarding God.
9. Error: Some argue that atheism partly stems from a failure to fairly and judiciously consider the facts 
10. State churches: In regards to the causes of atheism, rates of atheism are much higher in countries with a state sanctioned religion (such as many European countries), and lower in states without a sanctioned religion (such as the United States). Some argue this is because state churches become bloated, corrupt, and/or out of touch with the religious intuitions of the population, while churches independent of the state are leaner and more adaptable. It is important to distinguish "state-sanctioned churches," where participation is voluntary, from "state-mandated churches" (such as Saudi Arabia) with much lower atheism rates because publicly admitted atheism is punishable by death. 
13. Poor relationship with father: Some argue that a troubled/non-existent relationship with a father may influence one of the causes of atheism. Dr. Paul Vitz wrote a book entitled Faith of the Fatherless in which he points out that after studying the lives of more than a dozen leading atheists he found that a large majority of them had a father who was present but weak, present but abusive, or absent. Dr. Vitz also examined the lives of prominent theists who were contemporaneous to their atheist counterparts and from the same culture and in every instance these prominent theists had a good relationship with his father. Dr. Vitz has also stated other common factors he observed in the leading atheists he profiled: they were all intelligent and arrogant.
14. Division in religion: According to Sir Francis Bacon, atheism is caused by "divisions in religion, if they be many; for any one main division addeth zeal to both sides, but many divisions introduce atheism." 
15. Ignorance. Atheism is indirectly proportional to education; a scholarly study published in an academic journal titled the Review of Religious Research demonstrated that increased education is correlated with belief in God and that "education positively affects religious participation, devotional activities, and emphasizing the importance of religion in daily life." Sir Francis Bacon wrote: "A little philosophy inclineth man's mind to atheism, but depth in philosophy bringeth men's minds about to religion." 
16. Indoctrination and ease of life: Francis Bacon argued that atheism was partly caused by "Learned times, specially with peace and prosperity; for troubles and adversities do more bow men’s minds to religion."
Jewish columnist Dennis Prager has stated that one of the causes of atheism is the "secular indoctrination of a generation."  Prager stated that "From elementary school through graduate school, only one way of looking at the world – the secular – is presented. The typical individual in the Western world receives as secular an indoctrination as the typical European received a religious one in the Middle Ages." In addition, in communist countries (such as the former Soviet Union) atheistic indoctrination occurred in the educational system through such venues as schools, atheist museums, and clubs. Atheists and secularists rarely point out that universities such as Harvard, Princeton, Oxford, Cambridge, and many others were founded by Christians.

Education does influence Americans’ religious beliefs and activities, but the effects of education on religion are complex.”

- The more education people receive, the more religious they become?. Daily Mail (12 August 2011). “By analyzing data from a large national survey, sociologist Philip Schwadel of the University of Nebraska-Lincoln found that people tend to become more religious - by certain definitions - as they further their education. The survey also qualified what concept of God or a 'higher power' individuals held, as well as whether they had any doubts. Mr Schwadel said that: 'With more years of education, you aren’t relatively more likely to say, "I don’t believe in God," but you are relatively more likely to say, "I believe in a higher power."'”
