Was it Ancient Alien?
Or something in the Geology? I was watching a YouTube video on whether the bust of Nerfiti in Berlin Museum is a fake - I think it is - and one of the things which stuck me was the colour of the blue dye used. It is the same shade as the blue of the Native American necklace I am wearing, which came from Southern America, could this mean Ancient Aliens gave the knowledge to two cultures? Or could it be both areas are on the equator, and therefore share the geology ?
