Independent Egyptologist António Ambrósio challenges ancient history by claiming a lost supercivilization built the Great Pyramids at Giza in Egypt thousands of years before the pharaohs

A radical new theory is challenging everything we thought we knew about the Great Pyramids of Giza.

Independent researcher António Ambrósio, an Egyptologist from the Autonomous University of Barcelona, claims the iconic structures may be up to 12,000 years old — thousands of years older than the civilization that has long been credited with their construction.

If Ambrósio is correct, this would suggest a previously unknown “supercivilization” existed on Earth, one capable of engineering feats that modern humans have struggled to replicate.

According to him, the Egyptian pharaohs of the Fourth Dynasty simply appropriated these pre-existing structures rather than building them from scratch.

Clues Hidden in Plain Sight

Ambrósio’s argument hinges on several curious details.

Despite the pyramids being traditionally linked to Pharaohs Khufu, Khafre, and Menkaure, no royal mummies or burial items have ever been conclusively discovered inside the three main Giza pyramids.

The engineering itself raises questions.

The Giza pyramids feature stone cuts of extraordinary precision, almost perfectly level bases, and alignments with star constellations — achievements unmatched by smaller pyramids built during Egypt’s Fourth Dynasty, around 2500 to 2150 BC.

Additionally, the nearby Sphinx shows evidence of water erosion caused by heavy rainfall — a type of precipitation that hasn’t occurred in Egypt since roughly 5000 to 3000 BC.

This suggests that the site may have been exposed to environmental forces long before the rise of the Egyptian state in 3100 BC.

Questioning the Egyptian Claim

One piece of evidence often cited to connect Khufu to the Great Pyramid is the Khufu cartouche, a red-ochre hieroglyph found in a hidden chamber.

While mainstream Egyptologists consider it authentic, skeptics argue it may have been forged in 1837 by Colonel Howard Vyse.

“No mummy has ever been found in the pyramids of Giza,” Ambrósio explains.

“The discovery of a supposed sarcophagus of Khufu, found empty, does not prove that he built the pyramid — only that he claimed it.”

Subsequent Egyptian pyramids built after Giza were smaller, less accurate in construction, misaligned with celestial bodies, and made from inferior materials — a fact that strengthens the argument that the techniques used to build Giza’s pyramids were lost over time.

A Global Network of Megastructures

Ambrósio also points to ancient structures worldwide that bear remarkable similarities to Giza, suggesting a shared knowledge or influence.

Sites like Sacsayhuamán in Peru and Baalbek in Lebanon exhibit advanced construction techniques that mirror the precision and scale of the Giza pyramids.

He argues that the Fourth Dynasty pharaohs may have reused these ancient structures, while later dynasties attempted to replicate them without success.

Fringe researchers, including Graham Hancock and Robert Schoch, interpret these global patterns as evidence of an advanced civilization thriving around 10,500 BC — a period Egyptians called Zep Tepi, or “the First Time,” described as a golden age ruled by gods before humans assumed control.

Encoding Knowledge Across Time

Independent researcher Matthew LaCroix suggests this civilization may have embedded knowledge into monuments worldwide through geometry, symbolism, and architecture.

He notes that the pyramids at Giza are aligned beneath Orion’s Belt, hinting at a sophisticated understanding of cosmic cycles.

Recent discoveries of recurring T-shapes, step pyramids, and carved symbols on stones worldwide further suggest this culture may have existed as far back as 38,000 to 40,000 years ago.

What’s Next

Ambrósio’s findings have yet to be peer-reviewed, and mainstream Egyptology remains cautious.

Verifying the theory will require interdisciplinary research combining archaeology, geology, astronomy, and advanced dating techniques.

Ground-penetrating radar, 3D mapping, and refined carbon dating could reveal new evidence about who really built these iconic structures and when.

Regardless of its ultimate acceptance, this research is sparking renewed fascination with the origins of human civilization and the possibility of ancient knowledge far beyond what we previously imagined.

Summary

António Ambrósio proposes that the Great Pyramids of Giza were built not by Egyptian pharaohs but by an advanced, now-lost civilization up to 12,000 years ago.

He cites the lack of mummies, precise engineering, star alignments, and water erosion on the Sphinx as evidence.

Comparative studies of global megalithic structures, alongside Egypt’s own myth of Zep Tepi, suggest a worldwide network of advanced knowledge encoded into monuments.

While controversial and unreviewed, the theory invites a reevaluation of early human history and the mysteries of lost civilizations.
