The origins of the tale of the land of MU come from the works of augustus le plongeon ( British-American antiquarian ) after his visit to yucatan to research the mayan ruins he had come across the popol vuh of the k`iche ( a sacred book ). He went on to translate this book which told the story of an ancient continent, a civilisation much older than the ancient Egyptians that was present in the pacific ocean before a disaster struck and the ancient advanced civilisation was lost forever.
Some researchers have found ancient clay tablets that translate and state that after the destruction of this old advanced MU continent, the ancient civilizations of India, Babylon, Persia, Egypt, and the Mayas were merely the decayed remnants of MU colonies. The advanced technology was lost and the colonies rebuild elsewhere.
