1. Myth: Without God, life has no meaning. There are 1.2 billion Chinese who have no predominant religion, and 1 billion people in India who are predominantly Hindu. And 65% of Japan's 127 million people claim to be non-believers. It is laughable to suggest that none of these billions of people are leading meaningful lives.2. Myth: Prayer works. Studies have now shown that inter-cessionary prayer has no effect whatsoever of the health or well-being of the subject.3. Myth: Atheists are immoral.There are hundreds of millions of non-believers on the planet living normal, decent, moral lives. They love their children, care about others, obey laws, and try to keep from doing harm to others just like everyone else. In fact, in predominantly non-believing countries such as in northern Europe, measures of societal health such as life expectancy at birth, adult literacy, per capita income, education, homicide, suicide, gender equality, and political coercion are better than they are in believing societies.4. Myth: Belief in God is compatible with science. In the past, every supernatural or paranormal explanation of phenomena that humans believed turned out to be mistaken; science has always found a physical explanation that revealed that the supernatural view was a myth. Modern organisms evolved from lower life forms, they weren't created 6,000 years ago in the finished state. Fever is not caused by demon possession. Bad weather is not the wrath of angry gods. Miracle claims have turned out to be mistakes, frauds, or deceptions. We have every reason to conclude that science will continue to undermine the superstitious worldview of religion.5. Myth: We have immortal souls that survive death.We have mountains of evidence that makes it clear that our consciousness, our beliefs, our desires, our thoughts all depend upon the proper functioning of our brains our nervous systems to exist. So when the brain dies, all of these things that we identify with the soul also cease to exist. Despite the fact that billions of people have lived and died on this planet, we do not have a single credible case of someone's soul, or consciousness, or personality continuing to exist despite the demise of their bodies.6. Myth: If there is no God, everything is permitted.Consider the billions of people in China, India, and Japan above. If this claim was true, none of them would be decent moral people. So Ghandi, the Buddha, and Confucius, to name only a few were not moral people on this view.7. Myth: Believing in God is not a cause of evil.The examples of cases where it was someone's belief in God that was the justification for their evils on humankind are too numerous to mention.8. Myth: God explains the origins of the universe.All of the questions that allegedly plague non-God attempts to explain our origins still apply to the faux explanation of God. The suggestion that God created everything does not make it any clearer to us where it all came from, how he created it, why he created it, where it is all going. In fact, it raises even more difficult mysteries: how did God, operating outside the confines of space, time, and natural law 'create' or 'build' a universe that has physical laws? We have no precedent and maybe no hope of answering or understanding such a possibility. What does it mean to say that some disembodied, spiritual being who knows everything and has all power, 'loves' us, or has thoughts, or goals, or plans?9. Myth: There's no harm in believing in God.Religious views inform voting, how they raise their children, what they think is moral and immoral, what laws and legislation they pass, who they are friends and enemies with, what companies they invest in, where they donate to charities, who they approve and disapprove of, who they are willing to kill or tolerate, what crimes they are willing to commit, and which wars they are willing to fight.
