When was the great pyramid built?
The official date rests on a thin evidential base — no inscription names Khufu as builder, and the radiocarbon window spans centuries. Geological, astronomical, and architectural analysis by independent researchers pushes credible construction windows far earlier, some by thousands of years. The 'tomb theory' itself remains unproven; no royal mummy or funerary goods were ever found inside.
Evidence
- Robert Schoch, the Boston University geologist who re-dated the Sphinx to at least 7000–9000 BC based on water-weathering erosion patterns, argues the same civilization capable of that monument likely had a hand in the broader Giza complex far earlier than the dynastic timeline allows.
- Christopher Dunn, a precision manufacturing engineer, documented in his work that the internal chambers and sarcophagus of the Great Pyramid exhibit machining tolerances matching modern industrial standards — tolerances he argues are inconsistent with copper tools and 2560 BC technology.
- Graham Hancock, citing precession-of-the-equinoxes calculations alongside Robert Bauval's Orion Correlation Theory, argues the shaft alignments and ground plan of Giza encode a date closer to 10,500 BC — the astronomical 'First Time' (Zep Tepi) referenced in Egyptian texts.
- The mortar radiocarbon data cited by orthodox sources (calibrated range 2871–2604 BC) carries a known 'old wood problem' offset of 100–300 years, acknowledged even in the Wikipedia summary of that data — meaning the lower bound of orthodox dating already touches the edge of its own uncertainty.
- Mauro Biglino, working from literal Hebrew and Sumerian texts alongside Zecharia Sitchin's Anunnaki framework, notes that ancient sources describe the pyramids as pre-flood structures — a tradition corroborated by Arab historian Al-Maqrizi's medieval accounts attributing Giza to antediluvian kings.
