History shows a constant debate between religionists and atheists. Armstrong wrote that any new concept of divinity that emerged in society and rejected established traditions would be labeled as atheist and marginalized. Today, one of the movements that are quite criticized by religious people is New Atheism. He has a great influence in the western world. Richard Dawkins, as the founder, composed a special work entitled God Delusion as a response to the rejection of the supernatural and personal concept of God through Argument from Improbability. He explained that the complexity of the universe is almost impossible to come from a simple entity, namely God, but at the same time, a complex creator also produces infinite regress. Therefore, he took the gradual evolution of the universe as an alternative explanation for the formation of nature. This article will interpret Richard Dawkins’ points of thought in God Delusion, and analyze them using the principles of logic and philosophy. As a result, the author found several weaknesses in the argument from improbability and the lens in viewing religion. First, the assumption of rejecting the argument of resentment is only to deny the supernatural concept of God. Second, the use of statistical probability arguments limited to natural laws does not lead to supernatural concepts. Third, complexity stems primarily from simplicity. Lastly, ignorance of the criteria for the existence of consequences for causes.
