Similar references in multiple legends about giants and leviathans, together with huge anthropological skeletons with stretched skulls, as it was reported in mass media, allow the assumption, that the Celestial Giants on our planet were reality. Their number on Earth was small; therefore, archeological findings of this kind are rare.

The second difference between the Celestials and humans was that the former were semiaquatic species with intellect, which preferred living in water environment

In their books, multiple authors describe unusual archeological findings, which witness in favor of the assumption, that the knowledge of the ancient civilizations were far more advanced, than we all got used to think of it. Robert Kyle Grenville Temple, an American author, states in his book «The Sirius Mystery: New Scientific Evidence of Alien Contact 5,000 Years Ago» – published in Moscow, by Exmo, 2006, that Dogon people, Babylonians, Egyptians insist, that thecivilization was brought to our planet by intelligent Celestial species that came from the Sirius star system. According to the remaining descriptions, the aliens from Sirius were amphibians, the semiaquatic species. It is worth noticing also, that the detailed information about that alien visit to Earth, which remained intact until our days, is very precious from the astronomical point of view.

Dogon people also believe, that amphibian species established the human civilization. According to the ancient knowledge of the Dogon people, now living in the African republic of Mali, there is a small star (Sirius B) orbiting around the Sirius star system, and the small star, nevertheless, is massive enough to significantly influence the orbit of Sirius A. This small companion of the Sirius A is invisible with the naked eye, yet its parameters form the basis for Dogonian calendar. It was only recently, when the small star (Sirius B) was finally discovered with a large telescope; furthermore, the information from Dogon people, that the rotation period of this star around Sirius A equals 50 years, was confirmed fully! The newly-discovered star belongs to the white dwarf class. Among the strangest features of the starts in this class is their huge mass in combination with their small size. Those stars irradiate little light, but have incredibly powerful gravitation field.

According to the information from the Dogon people, there is yet another dwarf star (Sirius C), orbiting around the Sirius A star, and this third star is still unseen by modern telescopes; yet, Dogon people insist there are planetary systems inhabited by intelligent species around those three stars, and it is those intelligent species, which are our remote ancestors! The legends say those plants are inhabited by people with wings, with tails and with horns. The Dagon people has been knowing about those two Sirius satellites since maybe forever ago; furthermore, they know the orbital rotation periods; they state, that the closest satellite of Sirius consists of some lustrous and very heavy metal, a single grain of which weighs as much as «the total load that four hundred eighty donkeys can carry together». In addition to Dagon people, some other Sudanese tribes possess similar ancient knowledge: Bambara, Bozo and Manyika people, who are not spoiled by the modern civilization yet.

Egyptian legends often associate Sirius A with Osiris or Serapis (Royal Bull), eaten by Anubis (Celestial Dog), thus symbolizing Sirius B, the ultra-heavy dwarf star. We already mentioned, that in ancient time Sirius was often called the Dog Star. Sumerian goddess Bau with the head of a dog was the daughter of the god Anu, associated in Egypt with the dog-headed An-Pu, or Anubis, and also with the dog-headed god Hermes, who gave Celestial Knowledge to people. Plutarch also mentioned that Anubis is also a synonym for Cronus, the god, which was also associated with time, or Kronos. It is worth mentioning here, that Kronos or Cronus was the respected god of time, trade and fertility among ancient pagan Slavic people.
