Tiamat is the primordial salt-water sea of the Babylonian creation poem, the Enuma Elish: mother of the first gods, enemy of the young god Marduk, and the body from which he builds the sky and the earth. In The 12th Planet (1976), Zecharia Sitchin read her as a watery planet between Mars and Jupiter, shattered by the wandering planet Nibiru to form the asteroid belt and the Earth. Assyriologists read her as a mythic sea, and planetary scientists find no evidence that a planet ever existed where the asteroid belt now orbits.
Tiamat sits at the hinge of the Anunnaki debate. If the Enuma Elish is a theological poem, the battle is a story about Marduk's kingship. If it is encoded astronomy, as Sitchin argued and Billy Carson argues today, it becomes a record of the solar system's violent history written by people who could not have observed it. Setting the tablets, Sitchin's reading and the astronomy side by side lets readers judge the claim for themselves.

Who is Tiamat in the Enuma Elish?
Tiamat is the salt water, one of the two primordial beings who exist before anything else in the poem. Tablet I opens "when on high" (enuma elish), before heaven and earth had names, with Apsu, the fresh water, and Tiamat mingling their waters. From that union the first generations of gods are born. Her name is generally connected with the Akkadian word for sea, tâmtu, a link argued by Thorkild Jacobsen and Walter Burkert, and related to the Hebrew tehom, the "deep" of Genesis 1:2.
She is not a villain from the start. When the younger gods grow noisy, it is Apsu who plots to destroy them, and Tiamat who objects. Only after the god Ea kills Apsu does a faction of gods push her toward revenge. Popular retellings often make her a dragon, but the poem never describes her body in detail, and the Assyriologist Alexander Heidel cautioned that a dragon form cannot be assigned to her with certainty. For the wider cast of deities, see the guide to Sumerian gods and goddesses.
What happens in the celestial battle
The battle runs from the end of tablet I to tablet V and ends with Tiamat's body becoming the cosmos. At the close of tablet I she spawns eleven monstrous creatures, raises the god Kingu to command her army and gives him the Tablet of Destinies, the token of rightful rule over the gods. In tablets II and III, Ea and then Anu turn back from facing her, until Marduk, son of Ea, agrees to fight on condition that he be made king.
In tablet IV the gods arm him with a bow, a mace and lightning. Marduk makes a net to enclose Tiamat, posts the four winds so that nothing of her can escape, and creates further winds of his own, among them the Imhullu, the "evil wind." When Tiamat opens her mouth to swallow him, he drives the winds into her and shoots an arrow that splits her belly. Her army breaks, and Marduk takes the Tablet of Destinies from Kingu. Near the end of the tablet he splits her corpse in two, a moment the poem compares to splitting a fish, raises one half as the sky and sets guards so that her waters cannot escape.
Tablet V, partly broken, describes the ordering of the world. Marduk fixes the stations of the stars, gives the Moon its phases and builds the landscape from the rest of Tiamat: her head is heaped into a mountain, and the Tigris and Euphrates are made to flow from her eyes. In tablet VI humankind is created from the blood of the executed Kingu, and tablet VII closes with the fifty names of Marduk, one of which is Nibiru. The poem, tablet by tablet, is covered in the Enuma Elish explained.
How Sitchin turned Tiamat into a planet
Sitchin read the Enuma Elish as a cosmogony that described the formation of the solar system in coded form. In The 12th Planet, the gods of the poem become celestial bodies: Apsu is the Sun, Tiamat is a large watery planet orbiting between Mars and Jupiter, and Marduk is Nibiru, an intruder from outer space on a long elliptical orbit that brings it back every 3,600 years. Sitchin's wider claims, and the criticism they drew, are set out in who was Zecharia Sitchin.
In Sitchin's reconstruction, the "winds" that Marduk drives into Tiamat are Nibiru's moons, and the battle is a series of near passes and impacts. One strike splits Tiamat. One half is shattered and, in his reading, "hammered" into a bracelet in the sky, which he identified with the asteroid belt and with the Hebrew raqia, the firmament of Genesis. The other half, struck again, is pushed into a new orbit nearer the Sun and becomes the Earth. Kingu, the leader of Tiamat's host, is her chief satellite in this reading; dragged along with the surviving half, it becomes the Moon. Tiamat's other satellites, the "helpers" who turned their backs, become comets on reversed orbits. Nibiru itself is examined in Nibiru and Planet X explained.
What the asteroid belt actually tells us
The asteroid belt is too small and too varied to be the wreckage of a planet. Its total mass is estimated at about 3 percent of the Moon's (published estimates run from roughly 3 to 4 percent), and the dwarf planet Ceres alone holds close to 40 percent of that. A planet larger than Earth, as Tiamat would have to be if Earth were only half of her, would leave thousands of times more material behind than the belt contains.
Composition argues against a single parent body too. Asteroids include rocky, metal-rich and carbon-rich types that formed at different temperatures and distances from the Sun, a spread that is difficult to explain if they all came from one world. The model most planetary scientists accept is that the belt is a remnant of the disk of planetesimals that never finished forming a planet. Gravitational stirring by Jupiter, and to a lesser degree Mars, sped up collisions between the building blocks so that they shattered rather than merged, and simulations suggest the belt lost most of its original mass within its first hundred million years or so.
The idea of a destroyed planet between Mars and Jupiter is also older than Sitchin. After Giuseppe Piazzi found Ceres in 1801, the German astronomer Heinrich Olbers discovered Pallas in 1802 and suggested in a letter to William Herschel that the two might be fragments of a larger planet that had broken apart. In 1823 the German linguist Johann Gottlieb Radlof named the lost world Phaeton, after the Greek myth. As more asteroids were found, their orbits and makeup pointed away from a single explosion, and astronomers moved to the accretion model in the twentieth century.
Where the Moon really came from
The leading scientific account of the Moon's origin is the giant-impact hypothesis. Proposed by William Hartmann and Donald Davis in 1975, and independently by Alastair Cameron and William Ward in 1976, it holds that a Mars-sized body, now called Theia, struck the young Earth roughly 4.5 billion years ago, within the first 100 million years or so of the solar system. Debris thrown into orbit collected to form the Moon.
The evidence comes largely from the Apollo samples, whose oxygen and other isotope ratios are almost identical to Earth's rocks, and from the unusually high angular momentum of the Earth-Moon system. Here Sitchin's reading and modern science briefly share ground: both describe an early collision that shaped the Earth and gave it its Moon. They part company on everything else. In the giant-impact model the collision happens at Earth's orbit, the impactor is smaller than Earth, the Moon forms from debris rather than arriving as a captured satellite, and the asteroid belt plays no part.
What scholars say about Sitchin's translation
Specialists in ancient Near Eastern languages reject the planetary reading of the poem. Michael S. Heiser, who held a PhD in Hebrew Bible and Semitic languages from the University of Wisconsin-Madison and who died in 2023, spent years answering Sitchin text by text on his site sitchiniswrong.com, arguing that Sitchin's renderings of key Sumerian and Akkadian words do not match the standard dictionaries and that no cuneiform text describes a twelfth planet. The historian Ronald H. Fritze, in Invented Knowledge (2009), concluded that Sitchin presented evidence selectively and bent it to fit his conclusions.
On Tiamat specifically, Assyriologists point out that the poem is explicit about what she is: the sea, matched with the fresh water of Apsu. The split body forms the sky above and the waters below, a cosmology shared with other Near Eastern traditions, including the separation of waters in Genesis 1. Nibiru in the poem is a name of Marduk and an astral station linked to him, usually identified with the planet Jupiter, not an extra world beyond Pluto. W. G. Lambert, whose Babylonian Creation Myths (2013) is the standard edition, read the work as a theological and political composition that raised Marduk, god of Babylon, to the head of the pantheon, probably in the late second millennium BCE.
Billy Carson's reading
Billy Carson's position follows Sitchin's: the Enuma Elish is astrophysics told in the language of myth. In his reading, Tiamat was a real planet, Marduk was a real incoming body, and the "war in heaven" was a collision that reshaped the solar system. He treats modern findings on early planetary impacts as support for the idea that the ancients preserved knowledge of events far older than humanity.
In the podcast episode Mars, Tiamat and the War That Changed Earth Forever, the episode description sets out his version in detail: Tiamat as a world several times larger than Earth, her destruction scattering the material that became Earth and pushing Mercury and Venus closer to the Sun, and Mars carrying the scars of the conflict in its contrasting hemispheres, tilted equator and signs of an ancient flood. He also places the Babylonian battle alongside sky wars in Norse, Greek, Hindu and biblical traditions, reading the parallels as a shared memory rather than coincidence. The full narrative is laid out in the Anunnaki war in heaven, and his comparison of the tablets with space-agency science in the Enuma Elish and NASA.
These are his interpretations, offered next to the science above. Mars' contrasting hemispheres and ancient surface water are real, and are studied as the result of an early impact or internal processes, not the destruction of a planet between Mars and Jupiter.

Frequently asked questions
Was Tiamat a planet?
In the Enuma Elish, Tiamat is the primordial salt-water sea and the mother of the gods, not a planet. The planetary reading comes from Zecharia Sitchin's The 12th Planet (1976), which Billy Carson follows. No cuneiform text calls her a planet, and astronomers find no evidence that a planet once orbited between Mars and Jupiter.
Is the asteroid belt the remains of a destroyed planet?
Planetary scientists say no. The belt's total mass is only about 3 percent of the Moon's, its asteroids come in chemically different types, and models show it as leftover planet-building material that Jupiter's gravity kept from coming together. The exploded-planet idea dates to Heinrich Olbers in 1802 and was abandoned as the evidence grew.
What is the "hammered bracelet"?
It is Sitchin's term for the asteroid belt. He argued that the half of Tiamat shattered in the collision was "hammered" into a band of debris, and he linked this to the raqia, the firmament of Genesis. Assyriologists do not accept this reading of the Babylonian or Hebrew texts.
Who is Kingu, and did he become the Moon?
Kingu is the god Tiamat raises to lead her army; she gives him the Tablet of Destinies, which Marduk takes from him after the battle, and in tablet VI humanity is made from his blood. Sitchin read Kingu as Tiamat's largest satellite and claimed it became Earth's Moon. Science favors the giant-impact model, in which the Moon formed from debris after a Mars-sized body called Theia struck the early Earth.
What does Tiamat's death create in the Enuma Elish?
Marduk splits her body in two, raises one half as the sky and uses the rest to shape the earth. Tablet V says her head was heaped into a mountain and that the Tigris and Euphrates flow from her eyes. The scene explains the Babylonian world as the ordered remains of the primordial sea.
