A few sentences. What are the mistakes? Humanity has always thought about metaphysical questions. By metaphysic, I mean globally a lot of questions that we are not able to answer by observations or scientifical demonstrations. Evidentally, the questions and the answers which were brought have been evolving a lot since the beginning of their existences. For instance, since Aristote, the emergence of monotheism or the development of science have influence about the beliefs of people on this question.
