Each new book Dawkins becomes a bestseller and causes heated discussions. His work has played a huge role in reviving interest in scientific books addressed to a wide readership. Followed by Dawkins R. In the book, Dawkins argues that belief in a supernatural creator is a false belief that, like mania, does not change depending on the facts. He cites Robert Piercing's saying that 'when one person is obsessed with illusions' it is called insanity. When a lot of people are obsessed with illusions' it's called religion'. According to Dawkins, his goal was to convey to the reader the following thoughts: Atheists can be happy, balanced, decent and intellectually full people. Natural selection and similar scientific theories explain the world better than the 'God Hypothesis' by which the world was designed by a higher intelligence. Children should not automatically be considered supporters of the religion of their parents Terms such as 'Catholic child?' or 'Muslim child?' cannot be taken lightly. Atheists should not be ashamed of their beliefs because atheism is a sign of a healthy and independent mind.
