There is an Ancient Sumerian Cylinder Seal, believed to be around 4,500 years old that curiously seems to depict our Sun and twelve planets within our Solar System, one of them supposedly being Nibiru, the elusive planet lurking somewhere on the outer edges of the Solar System.
Akkadian Cylinder Seal VA/243. This seal was named like that because it is number 243 in the collection of the Vorderasiatische Museum in Berlin.
The Akkadian cylinder seal pictured above dates from the third millennium B.C. (it’s at least 4500 years old) and can be found at the State Museum in East Berlin catalogued under VA/243. It’s one of the most ancient cylinder seals that have been found. It shows the god Enlil granting the plow — the knowledge of agriculture — to humankind. Also interesting on this seal is what is said to be a depiction of our solar system in the top left. You can see eleven globes surrounding what appears to be the sun. Author Zecharia Sitchin spent a number of pages in his book “The 12th Planet” discussing and analyzing this depiction. Sitchin contends that this depiction shows our solar system with the various heavenly bodies in their relative sizes. We can see the 9 planets we know of today (assuming Pluto is also a planet), the moon (ancient civilizations also held our moon to be a planet), the sun and a 10th planet that we have yet to locate.
Sitchin’s depiction and interpretation thereof have embarrassed astronomers for the past quarter of a century, because it is just not possible for ancient peoples to have known about post-Saturn planets, to say nothing about one more yet to be acknowledged “unknown planet.” My explanation that the knowledge was provided by the Anunnaki (“Those who from Heaven to Earth came”) — Extraterrestrial visitors to Earth — is an even greater anathema to the scientific establishment.
