Anxious about the future, modern man questions his origins. Genesis, the biblical book of beginnings, no longer seems to answer his essential questions. Apparently, its data contradicts scientific statements, and its narratives have a legendary tinge... In this book, the author exposes the misinterpretation of churchmen who treated Genesis as if it were a book of science, thus opening themselves up to a corrosive criticism and leading too many Christians to relegate this text to the category of myths. The author shows that the intention of Genesis is, on the contrary, to demythologize the religious notions of Antiquity. From this study, the text of Genesis emerges full of life and capable of satisfying the modern demands of a necessary quest for origins. It remains a relevant discourse from God.
