Graham Bruce Hancock (born August 2, 1950) is a British writer who promotes unscientific ideas about ancient civilizations and imaginary lost lands. He claims that an advanced society with spiritual technology existed during the last Ice Age until comet impacts caused the Younger Dryas event around 12,900 years ago. Hancock believes that survivors of this disaster passed their knowledge to hunter-gatherer groups in places like ancient Egypt, Sumer, and Mesoamerica, leading to the rise of early civilizations.
Hancock was born in Edinburgh and studied sociology at Durham University. He later worked as a journalist for British newspapers and magazines. His first books focused on international development, including Lords of Poverty (1989), which criticized corruption in the aid system. Starting with The Sign and the Seal in 1992, he shifted to writing speculative stories about human history and ancient cultures, authoring 12 books, such as Fingerprints of the Gods and Magicians of the Gods.
Scholars say Hancock’s research into archaeological evidence, myths, and historical records resembles investigative journalism but lacks accuracy, consistency, and fairness. They call his work pseudoarchaeology and pseudohistory because they believe it favors preconceived conclusions, ignores context, misrepresents sources, and selects evidence that supports his claims while ignoring conflicting information. Hancock’s idea of an advanced Ice Age civilization is considered a version of the hyperdiffusionism theory, which has been proposed by other writers since the 19th century.
Anthropologist Jeb Card describes Hancock’s writings as paranormal and views his Ice Age civilization theory as a modern myth that focuses on secret and spiritual knowledge. Hancock claims members of this ancient society had psychic abilities and communicated with "powerful nonphysical beings" through the use of psychedelic substances. He presents himself as a figure who challenges the "dogmatism" of academics, arguing that his work is more valid than professional archaeology and offers a way to understand reality and spiritual aspects ignored by materialist science. However, his books have not been reviewed by scholars or published in academic journals.
Hancock has also written two fantasy novels and gave a controversial TEDx talk in 2013 about the psychoactive drink ayahuasca. His ideas have inspired films, and he hosted the Netflix series Ancient Apocalypse (2022), based on his theories. He frequently appears on the podcast The Joe Rogan Experience to share his claims.
Early life and journalism
Graham Bruce Hancock was born in Edinburgh, Scotland, in 1950. At the age of three, he moved to India with his parents, where his father worked as a surgeon. After returning to the United Kingdom, he completed his studies at Durham University and earned a degree in sociology in 1973.
Hancock wrote articles for British newspapers such as The Times, The Sunday Times, The Independent, and The Guardian. He helped edit the magazine New Internationalist from 1976 to 1979 and worked as a reporter for The Economist in East Africa from 1981 to 1983. His early books focused on economic and social issues in developing countries. His book Lords of Poverty: The Power, Prestige, and Corruption of the International Aid Business (1989) used his reporting for The Economist to argue that deeply rooted corruption made the international aid system unable to be fixed, calling it "inherently bad, bad to the bone, and utterly beyond reform." Some reviewers praised the book's strong criticism of global aid, but others disagreed with Hancock's conclusion that aid is inherently harmful.
Later, Hancock admitted to mistakes made during this time, including close personal relationships with Somali leader Siad Barre and Ethiopian leader Mengistu Haile Mariam. He wrote a positive article about Barre for The Independent, noting that the regime helped arrange parts of his trip and admitting that he "definitely made a mistake" by forming those connections. Hancock has stated that by 1987, he was "pretty much permanently stoned" because he believed cannabis improved his writing.
Later writing
In 1992, the publication of The Sign and the Seal: The Quest for the Lost Ark of the Covenant marked a change in the author’s career from writing news reports to creating books that explore connections between archaeological, historical, and cultural information. A 1995 article in The Independent explained that the author shifted in 1989 from working with the Barre regime to researching the Ark of the Covenant, which led to the writing of The Sign and the Seal. Later books by the author include Fingerprints of the Gods, Magicians of the Gods, Keeper of Genesis, The Mars Mystery, Heaven's Mirror (with Santha Faiia), Underworld: The Mysterious Origins of Civilization, and Talisman: Sacred Cities, Secret Faith (with Robert Bauval).
The author’s first novel, Entangled: The Eater of Souls, began a planned fantasy series in 2010. The story follows "two brave young women" who "do battle with a demon who travels through time." The author said the idea came from his experiences with ayahuasca, a plant medicine that gave him "a series of intense visions" that revealed the characters and plot. He described writing the novel as "tremendous fun," noting that it was free from the strict analysis of his non-fiction work. He joked, "What was there to lose when my critics already described my factual books as fiction?"
The Sign and the Seal describes the author’s investigation into how the Ark of the Covenant might have traveled from ancient Israel to Ethiopia. He traces a path through Elephantine and Tana Qirqos and connects the story to medieval Ethiopia and the Knights Templar. Jonathan Kirsch of the Los Angeles Times described the book as "part travelogue, part true-adventure, part mystery-thriller" but noted it was "a mix of amateur research and imaginative ideas." Kirkus Reviews highlighted the author’s claim that the Lost Ark of the Covenant "really exists" and framed the book as an extension of his earlier work on Ethiopia.
In Fingerprints of the Gods: The Evidence of Earth's Lost Civilization (1995), the author argues that an advanced society existed before the last Ice Age ended and that its survivors passed on knowledge about the stars and architecture to later cultures. He points to monuments in the Americas, Africa, and Asia as evidence of this inheritance. Archaeologist Garrett G. Fagan wrote that the book uses "artefacts, monuments, entire cities, or whole cultures" to support a conclusion without considering their historical context. Kenneth Feder noted that the author’s ideas repeat theories that have been discussed for many years and said the book offers nothing new.
The Message of the Sphinx: A Quest for the Hidden Legacy of Mankind (also known as Keeper of Genesis in the United Kingdom) is a book written by the author and Robert Bauval in 1996. It claims that the Sphinx and Pyramids were built as far back as 10,500 BC using astronomical data. The book starts with the idea that erosion patterns on the Sphinx were caused by heavy rain thousands of years ago. The authors use computer simulations to argue that the pyramids, along with nearby structures, represent the positions of stars in the sky during the vernal equinox in 10,500 BC. They call this moment "Zep Tepi," or "First Time," a term found in ancient Egyptian records. The book suggests that Egyptian pharaohs’ rituals mirrored the movement of the sun through the stars in this distant era and that a hidden "Hall of Records" from a lost civilization might be found by studying the Giza Plateau as a map of the ancient sky.
In The Mars Mystery (1997), the author and co-authors Robert Bauval and John Grigsby interpreted images of the Cydonia region of Mars as evidence of a Martian civilization destroyed by a disaster. They linked the "Face on Mars" to Egyptian mythology and compared a supposed Martian pyramid to Egyptian and Mesoamerican pyramids. They claimed the "Face on Mars" was a message to Earth, warning that a Mars-like disaster could happen to Earth unless people act to prevent it.
Talisman: Sacred Cities, Secret Faith, coauthored with Robert Bauval, focuses on "the stream of heterodox religious beliefs, from early Christianity to the 18th century." It discusses groups like the Corpus Hermeticum, Cathars, Rosicrucians, Freemasons, and Knights Templar. The book makes claims such as Paris being inspired by Egyptian mythology, links between Solomon’s Temple and the Twin Towers, and connections between the Star of David and The Pentagon. David V. Barrett called the book "a mish-mash of badly-connected, half-argued theories" and said the authors promoted an old idea about a Jewish-Masonic plot. Journalist Damian Thompson later called the authors "fantasists."
In Supernatural: Meetings With the Ancient Teachers of Mankind (2005), the author used David Lewis-Williams’ neuropsychological model to explain how ancient cave art may have been influenced by visionary experiences that helped shape human thinking.
In 2015, St. Martin’s Press published Magicians of the Gods: The Forgotten Wisdom of Earth's Lost Civilization. In this book, the author revisits his theory about an advanced civilization that existed before the last Ice Age and links it to a proposed event called the Younger Dryas impact, which he claims wiped out advanced survivors. He argues that ancient monuments contain warnings from that lost culture. Kirkus Reviews called the book "for the Art Bell addict" and "risible and sure to sell." Michael Taube of the Washington Times called it a "creative fairytale" while acknowledging its popularity. Geologist Marc J. Defant argued that the author builds "a narrative on conjecture and selective evidence" and that the Younger Dryas impact theory does not support the author’s global claims.
Television and media
Starting in the 1990s, Hancock hosted television documentaries that promoted his unscientific ideas. He appeared in The Mysterious Origins of Man (1996), wrote and presented Underworld: Flooded Kingdoms of the Ice Age (2002), and hosted Quest for the Lost Civilization (1998). In 2022, he presented Ancient Apocalypse, a widely viewed Netflix documentary series that critics and archaeologists called pseudoscience.
Hancock’s theories form the basis of Ancient Apocalypse, a 2022 Netflix documentary series. In the series, Hancock claims that an advanced civilization existed during the last ice age and was destroyed by comet impacts around 12,000 years ago. He argues that survivors of this civilization taught hunter-gatherers around the world about agriculture, monumental architecture, and astronomy. He uses ancient monuments and natural features as evidence for these claims and says archaeologists ignore or hide this evidence.
Archaeologists and other experts reject the series’ claims as pseudoscience. They say the series uses only a small amount of evidence and ignores evidence that contradicts Hancock’s ideas. Critics also say the series falsely accuses mainstream archaeology of conspiring against Hancock’s theories. Some archaeologists link Hancock’s ideas to harmful 19th-century white supremacist beliefs, which they say disrespect the ancestors of Indigenous peoples who built the monuments. A Maltese archaeologist who appeared in the series said her interview was edited to support Hancock’s claims. The Society for American Archaeology (SAA) called the series a documentary but argued it should instead be labeled science fiction. The SAA said the show unfairly attacks archaeologists, uses racist ideas, harms Indigenous peoples, and offers no real evidence for an advanced, global Ice Age civilization.
Netflix released the second season of Ancient Apocalypse: The Americas in October 2024, with actor Keanu Reeves joining the cast. The season explores sites across North and South America, including White Sands fossil footprints in New Mexico, large geoglyphs in the western Amazon, Rapa Nui, Andean sites like Sacsayhuamán, and Mesoamerican monuments such as Palenque and Chichen Itza. The series repeats Hancock’s claim that a sophisticated ice age culture shared knowledge about astronomy and engineering with later populations after a disaster. It also suggests connections between myths and symbols from different cultures.
Before the second season was released in July 2024, producers canceled planned filming in the United States after Indigenous groups objected to Hancock’s portrayal of Native histories. The Guardian reported that the production had permit issues at Grand Canyon and Chaco Canyon and moved filming to other countries.
Experts and science writers criticized the second season’s content. Johnny Loftus wrote in Decider that Ancient Apocalypse: The Americas uses real scientific research to support Hancock’s unproven theories. He said Hancock’s ideas are not supported by evidence and that many archaeologists believe Hancock is unfairly attacking scientific fields. Critics also said that the White Sands footprints do not prove a civilization taught people about technology, that Amazonian geoglyphs and terra preta reflect local developments, and that proposed connections between symbols are not based on testable evidence.
In 2013, Hancock gave a TEDx talk titled The War on Consciousness, where he described his use of ayahuasca, an Amazonian drink containing a hallucinogenic compound called DMT. He said adults should be allowed to use it responsibly for self-improvement and spiritual growth. He also said he used cannabis for 24 years but stopped after using ayahuasca in 2011. After the talk, TED moved the video to its main website to address concerns about the accuracy of Hancock’s arguments.
Hancock has appeared on The Joe Rogan Experience podcast multiple times. In April 2024 (episode #2136), he debated Flint Dibble, an archaeology professor from Cardiff University, who strongly opposed Hancock’s unproven ideas. Many of Hancock’s supporters said Dibble and mainstream science won the debate. Both Hancock and Dibble agreed that continued archaeological research would benefit humanity.
Pseudoarchaeology
Experts describe Graham Hancock's work as mixing chosen information with a strong disagreement toward "mainstream archaeology." They say his approach resembles investigative journalism but is not accurate, consistent, or complete. He uses myths, pseudoscience, old science, and research that only supports his ideas. Hancock encourages people to doubt archaeological experts and responds to criticism by claiming it is censorship, a pattern some of his supporters repeat by calling critics "disinformation agents."
Hammer and Swartz quote Hancock saying his goal is to challenge traditional history and strongly argue for the existence of a lost civilization.
Pseudoarchaeologists often mislead their audiences by presenting incorrect information, taking quotes from sources out of context, and hiding data that contradicts their claims. Historian Garrett G. Fagan, who studies Ancient Rome and criticizes pseudoarchaeology, points out two examples from Hancock's book Fingerprints of the Gods (1995):
Hancock's main idea is that an advanced civilization existed during the last Ice Age before a global disaster destroyed it. He claims a small group of survivors spread their knowledge worldwide, influencing early civilizations. He believes these societies could not have developed independently or reached similar ideas on their own. Scholars call this idea "hyperdiffusionism" and say it is based on Ignatius L. Donnelly's book Atlantis: The Antediluvian World (1882), which Hancock mentions as an influence. Researchers argue that this theory has no solid evidence, favors Western civilization, and oversimplifies complex cultural histories.
To explain the disappearance of his Ice Age civilization, Hancock supports the "Younger Dryas impact hypothesis," which most scientists do not believe. He claims the civilization was destroyed about 12,000 years ago by sudden climate change during the Younger Dryas period, which he says was caused by a meteor hitting Earth.
Hancock says survivors of the disaster traveled to places like Egypt, Mesopotamia, and Mesoamerica, where they taught hunter-gatherer communities about farming, building large structures, and astronomy. He believes ancient monuments contain encoded astronomical data meant to warn future generations. Critics say his story assumes the Ice Age civilization did not have writing, fails to explain why warnings differ across cultures, and relies on hidden messages that experts have ignored for years. Hancock argues that this knowledge was passed down through symbols.
Hancock believes these events are reflected in myths, such as Plato's story of Atlantis, and that the Atlanteans were remembered as "magicians and gods."
Hancock has accepted unusual theories about historic sites from other Atlantis supporters. For example, geologist Robert M. Schoch claims the Great Sphinx of Giza was carved over 11,500 years ago based on water erosion, and geologist Danny Hilman Natawidjaja says Gunung Padang is a 27,000-year-old Atlantean structure.
Scholars Olav Hammer and Karen Swartz write that Hancock's books are based on reinterpreting artifacts and myths in ways that ignore their original cultural and religious meanings.
In America Before (2019), Hancock writes: "In my view, the science of the lost civilization was primarily focused upon what we now call psi capacities that deployed the enhanced and focused power of human consciousness to channel energies and to manipulate matter."
Hammer and Swartz say Hancock describes his lost Ice Age civilization as using spiritual technology that uses consciousness to control matter. Anthropologist Jeb Card notes that America Before (2019) describes a "global sea-based society comparable with the late pre-industrial British Empire" whose knowledge "would seem like magic even today." He writes that Hancock claims the Atlanteans had psychic abilities and taught geometry, astronomy, and spirituality through rituals involving plants like ayahuasca and peyote to communicate with "powerful nonphysical beings."
Hancock also says meditation and psychoactive plants helped ancient builders move large stones, claiming granite blocks at the Great Pyramid of Giza were raised by "priests chanting," a scenario he links to sound waves. Archaeologist John Hoopes describes these ideas as religious beliefs tied to New Age movements.
Card says it is hard to evaluate Hancock using standard archaeology tools because he works in a paranormal context and his Ice Age civilization is a mythical story. He calls Hancock "not a failed version of an archaeologist" but a "successful mythographer of a post-science age," saying Hancock's theory is "a path to truly understanding reality and the spiritual elements denied by materialist science." Hammer and Swartz, who study new religious movements, describe Hancock as a "bricoleur who creates a myth from a mix of cultural elements."
Archaeologist Jason Colavito criticizes Hancock for using racist sources. He cites Ignatius L. Donnelly, whose "mound builder myth" claimed Indigenous peoples of the Americas could not have built large structures and instead credited them to white Atlanteans. Hancock says he does not agree with that idea but does not explain how capable Indigenous societies support his story of a lost civilization sharing advanced knowledge with them.
Although Hancock says the Atlanteans were Indigenous Americans, he wrote in Fingerprints of the Gods that they were "white [and] auburn-haired." He uses outdated race science to argue that pre-Columbian societies included "Caucasoids" and "Negroids," based on his interpretations of Indigenous art and mythology.
Hancock describes the Maya as "semi-civilized" with "generally unremarkable" achievements to support his idea that they inherited their calendar from an older society. He denies being racist and has supported Indigenous rights.
Hancock often promotes Robert Bauval's "Orion correlation theory," which claims the three largest pyramids at Giza were placed to mirror the three stars of Orion's Belt. Bauval says the pyramids align with the cardinal directions very precisely. However, astronomer Tony Fairall points out that the stars do not align correctly, missing by more than five degrees.
Hancock and Bauval's theory was the focus of the BBC documentary Horizon in 1999. The program criticized the idea by showing that the constellation Leo could be mapped to New York landmarks and argued that Hancock chose specific temples to support his claims. It concluded that "as long as you have enough points and don't need every point to fit, you can find any pattern you want."
After the broadcast, Hancock and Bauval complained to
