About the Author

Graham Bruce Hancock, bestselling author of America Before: The Key to Earth’s Lost Civilization, is a provocative alternative history researcher and journalist renowned for his controversial hypotheses about prehistoric advanced civilizations. Born in Edinburgh and educated in sociology at Durham University, Hancock’s career began in journalism, with roles at The Economist, The Guardian, and The Times.

His shift to exploring humanity’s ancient past produced seminal works like Fingerprints of the Gods and Magicians of the Gods, which argue that a sophisticated Ice Age society was obliterated by a cosmic catastrophe, reshaping global archaeology debates.

Hancock’s work blends archaeology, geology, and myth to challenge mainstream narratives, a theme central to America Before, which investigates pre-Columbian Americas’ enigmatic origins. A frequent guest on platforms like The Joe Rogan Experience and TEDx, he also created the Netflix series Ancient Apocalypse, reaching millions worldwide.

His ideas, though contested by academics, have fueled public fascination with lost civilizations. Hancock’s other notable books, including Underworld and Supernatural, further cement his status as a leading voice in speculative history. Ancient Apocalypse became a global streaming hit, underscoring his enduring appeal.

FAQs About This Book

What is America Before by Graham Hancock about?

America Before challenges mainstream history by arguing that advanced civilizations existed in the Americas tens of thousands of years earlier than traditionally believed. Graham Hancock presents archaeological and genetic evidence—like Amazonian earthworks aligned with stars and pre-Clovis sites such as Monte Verde—to suggest a sophisticated, forgotten culture was wiped out by a comet cataclysm around 12,800 years ago.

Who should read America Before by Graham Hancock?

This book is ideal for readers fascinated by alternative history, archaeology, and ancient civilizations. It appeals to those questioning conventional narratives about pre-Columbian America or interested in theories linking global ancient cultures. Critics of Hancock’s unconventional methods may find it contentious, but open-minded audiences will appreciate its interdisciplinary approach.

Is America Before by Graham Hancock worth reading?

Yes, if you enjoy speculative history backed by interdisciplinary research. Hancock synthesizes genetic studies, archaeological anomalies, and indigenous oral traditions to argue for a lost Ice Age civilization. While mainstream scholars dispute his conclusions, the book’s bold claims and accessible storytelling make it a thought-provoking read.

What evidence does Hancock present for advanced ancient civilizations in the Americas?

Key evidence includes:

• Pre-Clovis sites like Chile’s Monte Verde (14,000+ years old) and Pennsylvania’s Meadowcroft, challenging the "Clovis First" model.
• Amazonian earthworks showing sophisticated land management 8,000+ years ago.
• Star-aligned monuments such as Serpent Mound, suggesting astronomical knowledge. Hancock argues these point to a shared cultural legacy erased by catastrophe.

How does America Before address the "Clovis First" theory?

Hancock systematically dismantles the Clovis First paradigm (which claims humans arrived ~13,000 years ago) using sites like Bluefish Caves (24,000+ years old) and genetic data indicating multiple migration waves from Asia, Australia, and Europe. He asserts this rewrites the timeline of human settlement in the Americas.

What role does the Younger Dryas comet hypothesis play in America Before?

Hancock posits a comet strike 12,800 years ago caused the Younger Dryas cooling event, wiping out an advanced civilization. He cites nano-diamond deposits and megafauna extinctions as evidence, linking this catastrophe to global flood myths and cultural resets.

How does America Before connect Native American cultures to ancient civilizations?

The book highlights parallels between Native American shamanic visions and Egyptian afterlife beliefs, suggesting a shared ancestral knowledge system. Hancock also documents indigenous land-management practices in the Amazon, arguing they descend from advanced prehistoric techniques.

What criticisms has America Before faced?

Mainstream archaeologists critique Hancock’s reliance on controversial dating methods and speculative leaps. For example, his comet hypothesis is disputed, and sites like Göbekli Tepe’s connection to the Americas remain unproven. Critics argue he cherry-picks data to fit a sensational narrative.

How does America Before compare to Hancock’s earlier works?

Like Fingerprints of the Gods, it explores lost civilizations but focuses specifically on the Americas. The book expands on themes of catastrophic climate shifts and intercontinental cultural links, incorporating newer DNA and LiDAR technologies to support his theories.

What frameworks does Hancock use to analyze ancient sites?

Hancock emphasizes:

• Astroarchaeology: Aligning monuments with celestial events.
• Comparative mythology: Identifying shared flood myths.
• Anthropogenic landscapes: Evidence of human-shaped ecosystems, like Amazonian terra preta soil.

How does America Before redefine the Amazon’s history?

The book disputes the “pristine wilderness” myth, revealing 8,000+ years of indigenous agroforestry. Hancock cites terra preta (fertile human-made soil) and geometric earthworks as proof of large-scale, intentional land management—a stark contrast to European colonizers’ “savage” stereotype.

What modern technologies support Hancock’s claims in America Before?

LiDAR mapping exposed hidden Amazonian earthworks, while genetic studies show Australasian DNA in South America, hinting at ancient transoceanic contacts. Hancock also uses sediment cores to track climate shifts post-comet impact.
