This is a survey of some cosmogonic myths that explicitly raise the question of the beginnings in terms of enigma. Mud, light, desire, dream, illusion, such are some of the disturbing ways to begin a persuasive story. Something has to be said, a story to be made, and these myths are working in the same way as the story of the big bang addressed today to those who cannot understand it. But these stories are offering, still and always, a serious reflection on what is most simply human.
