Best-selling atheist books like Richard Dawkins’ The God Delusion and Christopher Hitchens’ God is Not Great suffer from this incoherence in varying degrees. They argue that God cannot exist because only material things exist. This is the naturalist worldview upon which atheism rests. By demonstrating that naturalism is false, it becomes easier to show why theism, not atheism, is the truly rational option.
Naturalism claims that only material things exist. And yet, it is self-evident that love, happiness, human rights, good and evil are real though immaterial. To be consistent, atheists are forced to argue that these things are just electrically charged chemical reactions inside the brain.
But if that were true, then there could be no such thing as “good” or “evil,” only behavior with which you agree or disagree. And if that were true, then there would be no use in appealing to “right” or “wrong” because those are nothing more than chemical processes inside the brain. In an atheist universe where God doesn’t exist, slavery, theft, murder, and cutting down rain forests would not be “evil” or “wrong.” They would simply be behaviors you dislike. Not even an atheist would want to live in that universe.
As is often the case, there's lots more stupid in the article.
