Penn Jillette is a famous celebrity and advocate for atheism in the USA. In an interview with 'Big think' he claims to have become an atheist by reading the Bible. 

This episode takes a critical look at the interview and reviews the Biblical ideas that Penn claims made him an atheist. A few truths emerge: Few people search for truth objectively, most atheists investigate the Bible only superficially, and people generally decide what they want to believe and then find evidence to support their belief. 

The words of the famous atheist Thomas Nagel explains it well: "I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers. It isn’t just that I don’t believe in God and, naturally, hope that I’m right in my belief. It’s that I hope there is no God! I don’t want there to be a God; I don’t want the universe to be like that.”(”The Last Word” by Thomas Nagel, Oxford University Press: 1997)”
