Dont know if it is true, but in book from "The Founders" at last chapter is described Life on other worlds that have or had some influence to Earth.
Pleiades are root race of humanity,
Venus is a place for beings in etheric realms for fifth and sixth density,
Jupiter has few hundred thousands souls considered "gatekeepers" seventh density or above,
Saturn includes structures made of rare metals and crystals 7 and 8 density are there,
Alpha Centauri has 5 planets ,one is inhabitet by 4-D humanoids-scientific and advance tehnology placethey have not evolved in spiritual awareness,bodies ar more perfected than on earth,
Tau Ceti has highly evolved humanoids,tall, slender light beings ( lvl density 3 -5),
Fomalhaut has various forms of intelligent life, some are insect-like,other seem more reptilian.Humanoid race exists at 7 density,ble-white translucent beingsand so on...... you can read about it in that book will not advertise it here cause it might be Cointel book i just dont know .Book feels right and positive but has much "differences " (couldnt find better word) than "C" scripts. Maybe a good question about "The Founders" could be presented to "C"-s.
