Antiquity can't be substitute of truth. Granted many of these claims may have strong correlations but I also hear a lot of nonsense that is as old as the civilization itself. Witchcraft is only one of them.
The 50,000 year deep indigenous knowledge being discussed there isn't magical sky friends, it's deep ecological knowledge about plants, animals, and where to find food and water where no outsiders would think to look.
