In this and subsequent books, Sitchin presented his translations of ancient Sumerian texts which tell an incredible story regarding the origins of mankind on Earth, stories that are completely different to those that most of us learned in school.
According to the ancient cuneiform texts, which are believed to be some of the oldest writings known to date, go back at least 6,000 years. These writings explain the history of a race of beings called the Anunnaki. The Anunnaki came to Earth from a planet in our solar system which is called Nibiru. Sadly, many people have never heard of it, because according to mainstream science the planet called Nibiru does not exist. However, according to Sitchin, the presence of Nibiru is very important for the past and future of humanity.
The orbit of Nibiru around the sun is believed to be extremely elliptical, and according to text, it is located far beyond the orbit of Pluto. It is believed that the elusive planet takes around 3600 years to complete one orbit around the Sun. Nibiru is believed to be the home planet of the Anunnaki.
Astronomers today suggest that there is in fact a planet called Planet X, located beyond the orbit of Pluto, a planet that explains the anomalies in the orbits of Neptune and Uranus, the New York times even talked about in 1982:
Something out there beyond the farthest reaches of the known solar system seems to be tugging at Uranus and Neptune. Some gravitational force keeps perturbing the two giant planets, causing irregularities in their orbits. The force suggests a presence far away and unseen, a large object that may be the long- sought Planet X. … The last time a serious search of the skies was made it led to the discovery in 1930 of Pluto, the ninth planet.
