Zecharia Sitchin (1920–2010) was an Azerbaijan-born, Israeli-raised writer who argued in The 12th Planet (1976) and the Earth Chronicles books that followed that the Anunnaki of Sumerian myth were flesh-and-blood visitors from a planet called Nibiru. In his account they arrived about 450,000 years ago to mine gold and later engineered modern humans as a labor force. Assyriologists and scholars of ancient languages reject his translations, but his books became the foundation of modern ancient-astronaut thinking.
Almost every conversation about the Anunnaki today runs through Sitchin, whether people realize it or not. Terms like Nibiru, the 3,600-year orbit and the gold-mining gods entered popular culture through his books, not through the tablets themselves. Knowing what he actually wrote, where his numbers came from and where specialists say he went wrong is the only fair way to judge the material, and the best way to separate what the ancient texts say from what has been read into them.
Who was Zecharia Sitchin?
Zecharia Sitchin was a journalist and business executive, not a trained Assyriologist, who spent decades studying the ancient Near East on his own. He was born on 11 July 1920 in Baku, then part of the Azerbaijan SSR, and grew up in Mandatory Palestine. He studied economics at the University of London and worked as a journalist and editor in Israel before moving to New York, where from 1952 he worked as an executive at a shipping company.
His interest in ancient texts ran alongside that career. He taught himself Sumerian and Akkadian, the languages of the cuneiform tablets, and presented himself as one of the few people able to read them in the original. That claim is central to his authority with readers and equally central to the objections of specialists, who argue that his readings do not match how the languages work. Sitchin died in New York on 9 October 2010 at the age of 90.
The 12th Planet and the Earth Chronicles
The 12th Planet, published in 1976, is the first volume of the Earth Chronicles series and lays out Sitchin's entire framework in one book. The title comes from his count of the solar system: the Sun, the Moon, the nine planets recognized at the time, and one more, Nibiru, make twelve celestial bodies.
The series continued with The Stairway to Heaven (1980), The Wars of Gods and Men (1985), The Lost Realms (1990), When Time Began (1993), The Cosmic Code (1998) and The End of Days (2007). Alongside the main series he published companion volumes: Genesis Revisited (1990), Divine Encounters (1995), The Lost Book of Enki (2002) and There Were Giants Upon the Earth (2010). The Lost Book of Enki is different in kind from the others. It is written as a narrative in Enki's own voice rather than as an argument from sources, and it should be read as Sitchin's reconstruction, not as a translated ancient text.
Across these books Sitchin draws on a wide mix of material: Sumerian and Akkadian myths, the Hebrew Bible, cylinder seals, temple architecture, and Egyptian and Mesoamerican sites.

What did Zecharia Sitchin claim?
Sitchin claimed that Sumerian and Babylonian texts are historical records of an advanced people from another planet who created humanity and founded civilization. The main pieces of his argument fit together as follows.
Nibiru and the 3,600-year orbit
In Sitchin's reading, Nibiru is a large planet on a long elliptical orbit that brings it into the inner solar system once every 3,600 years. He interpreted the Babylonian creation epic, the Enuma Elish, as a coded account of how the solar system formed, in which a collision between Nibiru's moons and a planet called Tiamat produced Earth and the asteroid belt. [Our Nibiru and Planet X explainer](/nibiru-and-planet-x-explained-sitchin-the-tablets-and-the-astronomy) covers the astronomy in detail.
The Anunnaki, gold and the making of humans
He argued that the Anunnaki, the gods of Sumerian myth, came to Earth from Nibiru about 450,000 years ago to mine gold. Around 300,000 years ago, weary of the labor, they genetically engineered Homo sapiens by crossing themselves with Homo erectus, creating a worker he identified with the lulu of the texts.
Enki, Enlil and the Flood
Sitchin cast the gods Enki and Enlil as rival half-brothers whose conflict drives much of human history, with Enki as the scientist sympathetic to humanity and Enlil as the stern commander. For how the two gods actually appear in Sumerian literature, see [Enki and Enlil, the two brothers of Sumerian myth](/enki-and-enlil-the-two-brothers-of-sumerian-myth). He also treated the Deluge as a real, physical event rather than a myth.
Nuclear war and the Lament for Ur
Among his most dramatic claims is that a nuclear conflict in the Sinai around 2024 BCE destroyed a spaceport there, and that the resulting fallout explains the "evil wind" of the Sumerian Lament for Ur and the collapse of Sumer. Mainstream historians read the Lament as a response to the fall of Ur at the end of its Third Dynasty, when the city was sacked by the Elamites.
The VA 243 seal
Sitchin pointed to a cylinder seal catalogued as VA 243, held in Berlin's Vorderasiatisches Museum, as evidence that the ancient Mesopotamians knew the full solar system. He read its central symbol as the Sun, ringed by smaller dots that he took to be the planets and the Moon, twelve bodies in total.
What the critics say
Specialists in ancient Near Eastern languages reject Sitchin's core readings, and their objections are specific rather than dismissive. The most sustained critique came from the late Michael S. Heiser, a scholar of ancient Semitic languages, whose website sitchiniswrong.com worked through Sitchin's claims text by text. The main points are these.
The word Anunnaki. Sitchin translated Anunnaki as "those who from heaven to earth came." Scholars read the name, from Sumerian a-nun-na-ki, as meaning something like "offspring of An" or "princely seed," a term for the divine family of the sky god, not a description of space travel. [Who were the Anunnaki?](/who-were-the-anunnaki-sumerian-texts-vs-ancient-astronaut-theory) sets the texts side by side with the ancient-astronaut reading.
Nibiru is not a hidden planet in the texts. No Sumerian text describes Nibiru as a planet beyond Pluto. The Akkadian word nēberu means something like "crossing" or "ford." In the astronomical compendium MUL.APIN, and in the Enuma Elish, where Nēberu appears among Marduk's fifty names, it is associated with Marduk's star, generally identified as Jupiter, or with a crossing point in the sky. It is also worth remembering that the Enuma Elish is a Babylonian composition in Akkadian, written long after the Sumerian period.
VA 243 shows a star, not the Sun. Critics point out that the central symbol on the seal is a star whose form differs from the standard Sumerian sign for the Sun, and that dots of this kind are common astral motifs on seals rather than a diagram of planetary orbits.
The orbit does not work. A planet crossing the inner solar system every 3,600 years would be dynamically unstable, and its gravity would have left measurable perturbations in the orbits of the known planets. Astronomers have found no such perturbations, and infrared sky surveys have not detected any such body.
The texts tell a different labor story. In the Old Babylonian Atrahasis epic, available in Stephanie Dalley's translation, the lesser gods rebel against the toil of digging watercourses, and humans are created from clay mixed with the flesh and blood of a slain god to take over that work. There is no gold mining and no crossing with another species. Genetics and the fossil record, meanwhile, trace Homo sapiens to a long evolutionary history in Africa.
Where the 3,600-year figure comes from
The 3,600-year cycle comes from the Mesopotamian number system and from the Babylonian priest Berossus, not from any tablet describing a planet's orbit. Sumerian counting was sexagesimal, or base 60, and one sar (Sumerian šár) equals 3,600, that is, 60 times 60. Berossus, writing his Babyloniaca in Greek in the 3rd century BCE, gave the reigns of the kings before the Flood in sars, producing reigns of tens of thousands of years.
The Sumerian King List records similarly enormous reigns before the Flood. Alulim of Eridu, the first king on the list, is credited with 28,800 years, or eight sars. Sitchin equated one sar with one orbit of Nibiru and used these reigns to build his timeline of Anunnaki rule on Earth. Mainstream scholars read the numbers as legendary or symbolic rather than as literal history. [Our Sumerian King List explainer](/the-sumerian-king-list-explained) walks through the list, its versions and how it has been interpreted.
Sitchin's legacy and cultural reach
Sitchin's books sold millions of copies in more than 25 languages, and his framework underpins much of today's ancient-astronaut media, including the television series Ancient Aliens. Ideas that now circulate as common knowledge, such as Nibiru as a returning planet, the Anunnaki as gold miners and humans as engineered workers, trace back to his books. For the wider movement he helped shape, see [ancient astronaut theory explained](/ancient-astronaut-theory-explained-origins-evidence-and-criticism).
One point is often misunderstood. The internet panics that predicted a Nibiru collision with Earth in 2003 and again in 2012 were not Sitchin's predictions. They came from other writers, and Sitchin distanced himself from the 2012 doomsday dates. His Nibiru was a cyclical visitor on a long orbit, not a planet about to strike Earth.
Billy Carson's reading
Billy Carson builds on the framework Sitchin opened up, but he does not treat Sitchin's books as the final word. In his work on the Anunnaki, Carson goes back to the primary translations, including the Electronic Text Corpus of Sumerian Literature (ETCSL) at Oxford and the work of Samuel Noah Kramer, Thorkild Jacobsen and Stephanie Dalley, and reads the texts for himself.
The result is a position that keeps the ancient-contact question at the center while departing from Sitchin on a number of details. Where Carson and Sitchin differ, Carson's approach is to test the claim against what the scholarly editions of the tablets actually say, rather than relying on Sitchin's paraphrases. That method of taking the Anunnaki seriously, while checking every step against the sources, runs through [Anunnaki: Ancient Secrets Revealed](/watch/anunnaki-ancient-secrets-revealed) on 4BK TV.
Readers who came to this subject through Sitchin will find that Carson's material covers much of the same ground, while placing more weight on the tablets themselves and on where the evidence supports, complicates or contradicts the popular story.

Frequently asked questions
Was Zecharia Sitchin a trained scholar?
Sitchin was an independent researcher, not a trained Assyriologist. He studied economics at the University of London, worked as a journalist and later as a shipping executive, and taught himself Sumerian and Akkadian. Specialists in those languages dispute many of his translations.
What is The 12th Planet about?
The 12th Planet (1976) argues that a planet called Nibiru orbits the Sun every 3,600 years and that its inhabitants, the Anunnaki, came to Earth, mined gold and engineered modern humans. It is the first book of Sitchin's seven-volume Earth Chronicles series. The title refers to his count of twelve bodies in the solar system: the Sun, the Moon, nine planets and Nibiru.
Did Sitchin predict that Nibiru would hit Earth in 2012?
No. The 2003 and 2012 Nibiru doomsday panics came from other sources, and Sitchin distanced himself from the 2012 dates. In his books Nibiru is a planet on a long, recurring orbit, not one on a collision course with Earth.
What does the word Anunnaki actually mean?
Scholars read the Sumerian name as meaning roughly "offspring of An" or "princely seed," referring to the gods descended from the sky god An. Sitchin's rendering, "those who from heaven to earth came," is not supported by Sumerian vocabulary or grammar, according to his critics.
When did Zecharia Sitchin die?
Zecharia Sitchin died in New York on 9 October 2010, aged 90. One of his last books, There Were Giants Upon the Earth, appeared the same year, and his Earth Chronicles series remains in print.
