Kemeticism which mean the black soil of Egypt. They believe they're gods.
Ancient Egypt is part of the Babylonian mysticism and Black soil which sounds like the black mat after the younger Dryas.
Ancient Egypt main population is underwater in the Mediterranean today. The idea of the mythology is that those of the Americas and Atlantis moved to Ancient Egypt which is older the Babylonia.
Ain Soph is the concept if you remove every physical and known about a substance what is left is the unconditioned state of all things. Which is why Ancient Egypt had a black and a white version of ISIS and other gods. Might be thought of as enter knowledge or esoteric.

Australian field is much older

I will look more into Kemeticism and Theosophical Society(Helena Blavatsky.). Both of their hatred for Christianity and direct links with ancient Egypt makes me believe you're on to something.
Thanks
Asks, "How many bizarre beliefs exist?"
Tau Tia L Douglass does a nice job at explaining the main ones. Though remember the Cabal(master infiltrators) shapes them all and believe they're direct competition.
