Atheism is one of the most dangerous absurd doctrines that have swept the world in the modern era. Its strength lies in the bodies that stand behind it and adopt its ideologies which are accompanied by the tremendous media momentum of the theses of its supporters based on scientific and non-scientific levels. And since the denial of the existence of the Creator is the main focus and central point which the atheists based their view towards the universe, life and man, this humble research came to discuss the claim of the existence of the world by pure chance, and try to explain this scientifically through the theory of natural selection and survival of the fittest developed by the English biologist Charles Darwin. The research also turned to talk about the contemporary forms of atheism, trying to grasp some of the manifestations of its existence in Islamic societies, while reviewing at the same time its destructive effects on the individual level on the one hand and on the human level as a whole on the other hand. Then the research was concluded by listing some of the most famous suspicions raised by advocates of atheism constantly which are followed by discussion and response to it.
