The Greek Reporter article (February 25, 2026, by Abdul Moeed) spotlights a fringe theory from independent researcher António Ambrósio (affiliated with the Autonomous University of Barcelona) in his non-peer-reviewed paper. It claims the Great Pyramids of Giza (and associated structures like the Sphinx) were constructed around 12,000 years ago (circa 10,000 BC) by a lost "supercivilization" with superior engineering capabilities, rather than by Fourth Dynasty pharaohs (Khufu, Khafre, Menkaure) around 2600–2500 BC as mainstream Egyptology holds. The pyramids, per this view, were later "appropriated" or claimed by the Egyptians, who then attempted (but failed) to replicate them in subsequent builds.
Key Arguments from Ambrósio's Thesis
Ambrósio highlights several anomalies to support an older origin:
Engineering Superiority: The Giza pyramids demonstrate exceptional precision — near-perfect base leveling, massive multi-ton blocks cut and fitted with minimal gaps, and astronomical alignments (e.g., to cardinal points and constellations). Later Old Kingdom pyramids are smaller, steeper-sloped, and structurally inferior, suggesting the Giza trio represent a peak that subsequent Egyptian builders could not match or even approach.
No Burial Evidence: The three main pyramids contain no mummies, burial goods, or definitive proof of pharaonic interment. The Great Pyramid's "sarcophagus" is an empty stone box; Ambrósio suggests Khufu may have simply inscribed his name (via disputed red-painted hieroglyphs in a relieving chamber, possibly added later) to claim an existing monument.
Sphinx Weathering: The Great Sphinx shows deep vertical erosion patterns consistent with prolonged heavy rainfall exposure — conditions absent in Egypt's arid climate since before ~3000 BC (end of the "African Humid Period"). This implies the Sphinx (and by extension the Giza plateau) predates dynastic Egypt by millennia.
Global Megalithic Parallels: Similar massive, precision-cut stonework appears at sites like Sacsayhuamán (Peru) and Baalbek (Lebanon), hinting at shared ancient knowledge from a single advanced source.
Egyptian Mythology Link: The concept of Zep Tepi ("First Time") — a mythical golden age of divine order before human kings — could reflect memories of this real supercivilisation, destroyed or lost around the end of the last Ice Age (~12,000 years ago).
The article notes related "controversial" claims, such as Italian researchers proposing a vast underground complex (shafts, chambers, possibly over 2,000 feet deep) beneath Giza, potentially supporting hidden older structures.
Broader Context and Alignment with Alternative Theories
This narrative echoes long-standing alternative history ideas popularised by figures like Graham Hancock (e.g., in Fingerprints of the Gods and Netflix's Ancient Apocalypse) and geologist Robert Schoch (Sphinx water-erosion hypothesis). They posit an advanced Ice Age civilization, wiped out by cataclysmic floods/comet impacts around 10,900 BC (Younger Dryas event), that disseminated knowledge to emerging cultures, explaining "impossible" feats like Giza's precision without wheels, iron tools, or large-scale writing in mainstream timelines.
The piece is neutral/speculative: it presents Ambrósio's paper as intriguing but fringe, acknowledges mainstream rejection (pyramids built ~2600 BC via ramps, copper tools, organized labor, backed by worker villages, quarry marks, and carbon-dated mortar), and calls for "further investigation" without endorsing it outright. Tone is sensational yet balanced, fitting Greek Reporter's mix of archaeology and alternative topics.
Assessment: Intriguing but Fringe
Mainstream archaeology dismisses such claims due to:
Overwhelming evidence tying Giza to Khufu's era (e.g., Khufu's boat pits, worker graffiti, papyri logs of stone transport).
No artifacts or inscriptions from a 12,000-year-old high-tech society.
Sphinx erosion explained by wind/sand, salt exfoliation, or occasional ancient rains — not requiring pre-dynastic builders.
Global megaliths show independent development, not unified supercivilisation tech transfer.
Ambrósio's work lacks peer review and relies on reinterpretation rather than new digs or dating. It fuels perennial fascination with "what if" ancient history but remains outside consensus. The article taps into ongoing debates (e.g., recent Giza scans revealing voids/corridors), keeping the mystery alive while highlighting how pyramids continue challenging our understanding of human ingenuity, whether 4,500 or 12,000 years old. Still, it is interesting speculation, a diversion from war.
