Can we find the myths of prehistory? It has often been said that myths and tales have “gone through the centuries”, or even that their transmission goes back to prehistoric times. How can we prove such statements? What is really going on? Can we really go back that far in an oral tradition? We will see that it is possible to show that certain myths of origin have been transmitted for tens of thousands of years and that it is even possible to find their paths of diffusion on the globe. Some of them have accompanied humanity from the beginning, through all its wanderings. The painters of Lascaux probably knew them, and they are still told today.
