Here are my non-canonical ideas about the ALIEN Universe:
The Mala'Kak were (are) an extraterrestrial species of intelligent elephantine, humanoid aliens with adults standing about 25' tall. They have a culture and civilization that is millions of years old, and their origin is mysterious. They may be from another area in the Milky Way galaxy or even from another galaxy -- no one knows for sure. Millions of years ago, they began to visit earth. At some point, they began to take primitive humans away as pets, to breed and experiment upon, mostly in a benevolent way. The Mala'Kak were long-lived but beginning to go extinct, and they thought human species were candidates to take over for them as benevolent and intelligent overseers of the universe. The Mala'Kak placed human beings on exoplanets with conditions very similar to earth, as well as some plant species necessary to human survival like wheat and animal species that could be hunted. This is why there are very human-like creatures and other earth-like life on exoplanets that would later be called Arcturus or Paradise/Planet 4 when later discovered. The Mala'Kak were mostly beneficent or neutral overlords, watching their pet humans develop and checking in on them from time to time, but with a special focus on the humans of Paradise, who were later called the Ossians based upon a tablet of hieroglyphs found on a planet in orbit around Tanaka's Star. More than any other humans, the Mala'Kak tampered with the DNA of the Ossians to try to perfect them -- to make them the best they could possibly be -- and the Ossians developed over hundreds of thousands of years to become 10-12' tall, nearly hairless, muscular, and highly intelligent. The Mala'Kak visited the Ossians on Paradise frequently in juggernaut ships hovering over their cities, and that became part of their religion. Most Ossians continued to hold them in god-like reverence. Some Ossians developed science and technology and with their own disc-shaped spaceships began to visit other star systems. The religion of the Ossians was based upon moral and physical perfection and sacrifice. In 12,000 BC, the Ossians visited earth in one of their disc-shaped ships and one of their number sacrificed himself to give his 'divine' DNA to improve life on earth. This was an age old religious tradition of their world, one in which they tried to visit the worlds of other men and attempted to pass on their gifts. Later, they also visited these lesser men to teach them things they have learned and tell them where they were from. They gave them crude star maps of sorts, and encouraged the men of other worlds to reach for the stars and try to come visit them someday, when they were ready.
