The human species supposedly originated from a planet in the stellar constellation of Lyra. Over time, the human species spread to other planets in our Galaxy, forming notable colonies in the Pleiades cluster, which is said to be inhabited by many human beings on multiple planets. Subsequently these colonies formed their own "Pleiadian Federation", itself a subset of the greater galactic community which of course includes other humanoid and non-human life forms dedicated to serving God, our Creator.
The Pleiadian civilization itself sent ships to form other colonies, the nearest to us being the one on the different vibration of Venus (NOT the searing inhospitable rock that we see, but a place on another frequency, so-called "Heaven") and the one that used to exist on Earth. The Earthly colony was called Atlantis, which was located in the Atlantic ocean until it perished in the Great Flood 12,000 years ago as explained in the Bible. The "Bermuda Triangle" mystery was in fact malfunctioning Atlantean portal technology which caused the disappearance of various ships and aircraft in the past century.
After the catastrophe called the Great Flood, the able survivors left the Earth. Some went back to the Pleiades, some stayed in their spaceships orbiting Earth waiting for the new civilizations to form. After the unfortunate cavemen went out of their caves and formed the civilizations of Sumeria, Maya, Greece etc. the influence of extraterrestrial humans was always with them, allowing for development of agriculture, science, pyramid construction and spiritual wisdom, most notably those offered by incarnated extraterrestrial spiritual masters like Buddha or Jesus Christ. The exact origins of these caveman humans (our closest ancestors) are also shrouded in mystery, some say we are all genetically engineered reptilian Nephilim slave miners, some say Pleiadian humans "seeded" our Neanderthal race with proper spiritual DNA, others say we are simply Pleiadians who lost access to space tech (until Bob Lazar's c-c-c-combo breaker).
Before and after the disaster, an evil secretive group called the Satanic Cabal was always lurking in the shadows, careful not to have its presence or alliances known to anyone. The rest is more or less known history…
