People might stop believing in God because of:
1) Peer influence. In high school, for example, the one or two religious believers in a class may be subject to ridicule.
2) Convenience; desires. People might decide they don't need "bothersome" rules, or limitations to their personal pleasure.
(We see how this lack of self-discipline often proceeds to bring about epidemic obesity, drunkenness, divorce rates, violence etc.)
3) Lack of proper information. People may have heard inaccurate notions about God. They've picked up tidbits, jokes, and "sound-bites," and on such solid authority they come to dismiss the entire topic.
4) Unfortunate experiences. Many have had personal hardships, or a harsh religious upbringing or education, and as a consequence may retain an unhappy feeling towards belief, without realizing that emotions and proofs are two different things.
5) Many come to think that science, and specifically Evolution, have proved that there is no God. They don't comprehend that even if Evolution was an unquestionable fact, it would not automatically follow that God isn't there. They also seem unaware that there are a significant number of highly-qualified scientists who do not believe in Evolution.
6) Stereotyping. People call us "religious nuts," "Bible-thumpers," etc.; so the average layperson may get a negative feeling toward all belief.
