In his book There Were Giants Upon the Earth (2010), Zecharia Sitchin
offers a radical reinterpretation of human history by blending ancient Sumerian mythology with biblical texts. He argues that the "giants" mentioned in Genesis 6:4 were actually the Anunnaki, a technologically advanced extraterrestrial race from the planet Nibiru. The Core Argument: Genetics and the
Sitchin posits that the Anunnaki arrived on Earth approximately 450,000 years ago to mine gold, which they needed to repair their own planet's atmosphere. To automate this grueling labor, he claims they genetically engineered the first humans by mixing their own DNA with that of Homo erectus. Key points of his theory include:
There Were Giants Upon the Earth by Zecharia Sitchin explores the theory that the Anunnaki, an advanced race from Nibiru, genetically engineered human ancestors. Sitchin argues that ancient myths of "giants" are based on these extraterrestrial beings, citing evidence from Sumerian texts and the Royal Tombs of Ur.

Zecharia Sitchin's " Hubo gigantes en la tierra " (originally There Were Giants Upon the Earth) is the final major work in his "Earth Chronicles" series. The book serves as a detailed synthesis of his lifelong theory that humanity was genetically engineered by the Anunnaki—extraterrestrials from the planet Nibiru—and that ancient myths are historical records of their presence. Core Themes and Arguments
Genetic Engineering: Sitchin argues that the biblical "Elohim" were the Anunnaki, who created "The Adam" roughly 300,000 years ago by mixing their genes with existing hominids.
The Nephilim and Giants: He interprets the biblical "Giants" (Nephilim) as the offspring of intermarriage between Anunnaki and humans, identifying them with famed demigods like Gilgamesh and the Deluge hero Utnapishtim (Noah).
Physical Evidence: A central part of the book focuses on the Royal Tombs of Ur. Sitchin claims that two specific tombs belong to an Anunnaki goddess and her demigod spouse, suggesting that DNA from these remains could provide definitive proof of alien intervention.
The Quest for Longevity: By studying these demigods, Sitchin suggests we might unlock ancient secrets related to health, longevity, and the "Missing Link" in human evolution. Reader and Critical Reception

Hubo Gigantes en la Tierra There Were Giants Upon the Earth represents the "crowning oeuvre" of Zecharia Sitchin ’s controversial Earth Chronicles
. In this final work, Sitchin attempts to bridge the gap between ancient mythology and physical science by investigating the existence of demigods—the "giants" or Nephilim mentioned in the Bible—as literal, biological descendants of extraterrestrials known as the The Core Theory: From Myth to DNA
Sitchin argues that the "gods" of Sumer and Babylon were actually visitors from a distant planet called
. According to his interpretation of ancient texts, these beings genetically engineered the first human (the "Adam") roughly 300,000 years ago by mixing their own DNA with that of primitive hominids.
The focus of this specific book is the "intermarriage" described in Genesis: the "sons of God" taking the "daughters of men" as wives. Sitchin identifies these offspring as the of legend, such as:
: The legendary Mesopotamian king obsessed with attaining the longevity of his godly ancestors. Utnapishtim
: The hero of the Babylonian Deluge story (the precursor to Noah). The Quest for Physical Proof

In his final major work, Hubo gigantes en la tierra (There Were Giants Upon the Earth), Zecharia Sitchin
provides a definitive synthesis of his "Ancient Astronaut" theory, focusing on the genetic and historical evidence of the Anunnaki. Published in 2010 shortly before his death, the book serves as a "detective story" that attempts to bridge the gap between biblical text, Sumerian mythology, and modern genetics. Core Themes and Discoveries
The narrative centers on the biblical verse from Genesis 6:4: "There were giants in the earth in those days...". Sitchin argues that these "giants" were not metaphorical figures but the Anunnaki—extraterrestrial beings from the planet Nibiru.
Genetic Engineering: Sitchin posits that humans are "descendants of demigods," created approximately 300,000 years ago when the Anunnaki combined their own DNA with that of an existing hominid (Homo erectus) to create a worker race.
The Royal Tombs of Ur: A significant portion of the book is dedicated to the Royal Tombs of Ur. Sitchin claims that these tombs—specifically those of Queen Puabi—contain the remains of an Anunnaki goddess and her demigod spouse. SEO / Metadata for this Feature:
Physical Proof of Alien DNA: Sitchin proposed that testing the DNA of remains from the Royal Tombs could provide conclusive scientific evidence of "alien DNA," potentially identifying the "Missing Link" in human evolution and revealing the secrets of extraterrestrial longevity. Summary of the Anunnaki Presence
According to Sitchin's translations of Sumerian and Akkadian tablets:

Did giants literally roam the Earth according to Zecharia Sitchin? Yes, absolutely. He was not speaking metaphorically.
But whether you believe his translations or dismiss them as creative fiction, one fact remains: the question of “hubo gigantes en la tierra” touches a deep human fascination with our own origins. Sitchin offers a grand, coherent, and thrilling narrative—one where giants are not monsters, but evidence of a cosmic family tree.
For the believer, the PDFs and books contain a hidden history of humanity. For the skeptic, they are a masterclass in how to reinterpret ancient myth for a modern age.
Either way, the giants of Sitchin’s Earth are not easily forgotten.
The Bible mentions them briefly but ominously: “There were giants (Nephilim) on the earth in those days.” (Genesis 6:4). Mainstream archaeology dismisses them as mythology or a misinterpretation of the Hebrew word Nephilim (meaning “those who fell” or “fallen ones”).
But for decades, the late author Zecharia Sitchin argued something far more literal. In his bestselling The Earth Chronicles series, Sitchin claimed that giants—real, flesh-and-blood beings of immense stature—once walked the Earth. Not as fairy tales, but as a genetic experiment gone wrong by ancient astronauts from the planet Nibiru.
