Earth Chronicles Books in Order

The Earth Chronicles gathers seven of Sitchin’s best-known books into one long argument about human origins. Rather than treating myth as poetry, he reads Sumerian, Babylonian, and biblical stories as historical records, especially when they describe gods arriving from the sky.

Everything turns on his claim that an extra planet, Nibiru, periodically swings through the solar system, bringing with it the godlike Anunnaki who once mined Earth’s gold and engineered humankind as a worker race.

The 12th Planet lays out that cosmology and the first contacts between Anunnaki and early humans, reconstructing a violent early solar system and the creation of Homo sapiens. The Stairway to Heaven turns to humanity’s search for immortality, tracing it to a “Land of the Gods” tied to the pyramids, the Sphinx, and what he sees as a spaceport in the Sinai.

The Wars of Gods and Men moves the story into an era of rival factions and open conflict among the gods, interpreting Mesopotamian and biblical tales as descriptions of real wars that culminated in the nuclear devastation of a Sinai launch site and nearby cities. The Lost Realms shifts focus to the Americas, arguing that Olmec, Maya, and Andean sites were founded or guided by the same visitors from Nibiru.

In When Time Began Sitchin follows the origins of astronomy, astrology, and sacred calendars, linking ziggurats, Stonehenge, and New World monuments to a coordinated effort to track changing celestial ages and Marduk’s rise. The Cosmic Code then looks for hidden messages in Hebrew letters, numbers, and prophetic texts, while The End of Days compares upheavals in the distant past with modern crises and develops a cyclical “celestial time” that, he argues, underlies end-time prophecies.

Several companion works orbit the main sequence. Genesis Revisited sets modern science beside ancient creation stories, Divine Encounters reinterprets visions and angels as meetings with the Anunnaki, The Lost Book of Enki retells the saga in Enki’s voice, The Earth Chronicles Handbook serves as an encyclopedic guide, and There Were Giants Upon the Earth concentrates on demigods and alleged traces of alien DNA. The result is a sprawling alternative history that many scholars criticize as pseudoscience but that has attracted a large, loyal readership and helped shape modern ancient-astronaut pop culture; new readers usually get the clearest sense of the argument by starting with The 12th Planet and then following the books in publication order.
