The term “Nibiru” comes from the Sumerian cuneiform tablets and writings dating 5,000 years old. The term Nibiru means “Planet of the crossing”, and it’s cuneiform sign was often a cross, or various winged disc. The Sumerian culture is the first recorded civilization on earth, in the fertile lands between the Euphrates and Tigris rivers, at the southern part of today’s Iraq.
Some scientists like Zecharia Sitchin and Jason Martell believe that the observations of ancient astronomers provide proof that Nibiru is an actual planet or brown dwarf in our solar system. These claims are for the most part dismissed as fringe science or pseudoscience by the mainstream scientific communities of archaeology and astronomy. However evidence is slowly emerging to show correlations that cannot be dismissed. The ancient knowlege given to us in the Sumerian tablets portray elaborate celestial understandings incomprehensibly beyond ancient technological capabilities. In other words, the detailed graphing of our 9 currently recognized planets was created 6,000 years ago, while modern science has only discovered our outermost two planets in the last 150 years. The ancients simply did not have the technology to view the skies, namely powerful telescopes, yet they recorded size, position, and movement. They also include in their tablets the inclusion of a tenth planet roughly 4 to 8 times the size of the Earth, or rather, the size of Jupiter. It seems only recently modern science has confirmed what the ancients already held to be fact.
