There is no God, there are no Gods. In the course of the history of mankind so far there have been hundreds of different conceptions of God. On the basis of two central stories from the Abrahamic conception of God I show here that these are largely irrational contents. First, what are gods anyway? There are many, but not too different definitions of the term God. Let us take the following definition, others are similar to it: A god is a supernatural being or a higher power. In the doctrine and practice of many religions, special qualities are attributed to a god; among other things, being the first origin or creator or shaper of all reality. With the definition one sees clearly that it is a myth of the beginning. It is an arbitrary setting without plausible explanation. The myth of the beginning forms the unquestioned starting point of religious thinking. Ideas about God and spirits are from the pre-scientific time, they are mostly irrational ideas. In the pre-scientific time there were many phenomena that could not be explained and were attributed to the work of gods and spirits, such as thunderstorms or floods. Often, separate deities were responsible for different areas, such as gods of war and fertility. In the course of human history, there have been hundreds of different conceptions of God, such as the jackal-headed „companion of the dead“ Anubis in ancient Egypt or in Christianity God the Father, God the Son, God the Holy Spirit. At present the God conception of the Jews, Christians and Muslims, the Abrahamic God, dominates. On the basis of two central stories from the Abrahamic conception of God it is shown here that the contents are largely irrational. So „God“ is supposed to have tested the tribal leader of a shepherd people, Abraham, for his loyalty to him by seemingly asking him to kill a son. It is a macabre story that is still impressed upon believers today. The story portrays a cold God, a monster. In a second mystical story, the Abrahamic god destroys two cities, Sodom and Gomorrah. The reason, the people act against his moral concepts. Today one would look for such a „god“ as a mass murderer with the police. From today’s perspective, it’s a story with a psychopathic god. In a long struggle the sciences had to establish themselves against the massive resistance of the great religions Christianity and Islam. The „scribes“ of the „Holy Books“ tried to make their sacred books the linchpin of human existence, everything was to be subordinated to the fairy-tale like and often abstruse contents of their strongly limited horizon, focused on ancient texts. I am happy to comment in detail on individual aspects of the religious world view from a scientific point of view.
