¢ why might the paintings at lascaux be considered sacred?

A number of anthropologists as well as art historians make a theory that the paintings are possibly an account of hunting success in the past. Another theory they have is that the paintings could be a representation of a mystical ritual in order to improve future hunting endeavors which is supported by the overlapping images of a group of animals in the same cavern location while another group of animals suggests that one part of cavern was more successful for foretelling a bounty hunting excursion.
