Study Places Great Pyramid 35,000 Years Before Official Timeline
A recent study by engineer Alberto Donini, published on Zenodo, proposes that the Great Pyramid of Giza was constructed between 8,954 BC and 36,878 BC, a range spanning nearly 28,000 years. Academic chronology places its construction around 2,580 BC. The discrepancy is vast, and the method used—thermoluminescence dating—has reignited doubts about the reliability of stone dating techniques.
A Range That Covers Everything
The study assigns a 68.2% probability that construction occurred within this interval. In other words, there is nearly a 70% chance the pyramid was erected over a period of 27,900 years. As one analyst noted, such a wide margin allows for few definitive conclusions. "Nearly 70% certainty that the pyramid was built within a 27,900-year timeframe. Now that is scientific rigor," a commentator joked. The main criticism is that thermoluminescence, while applicable to inorganic materials, depends on multiple parameters (temperature, humidity, environmental radiation) that vary significantly over tens of thousands of years, especially in a region where the climate shifted from a wet savanna to an arid desert.
The Climate and Erosion Problem
Several analyses pointed out that 35,000 years ago, the Egyptian landscape was radically different: rivers, abundant vegetation, and a cooler climate. The Sphinx and the pyramids themselves show erosion patterns that some attribute to heavy rainfall rather than just wind and sand. This suggests they could be much older than currently believed. However, Donini’s method measures current erosion and projects it linearly backward, ignoring climatic changes. As one analyst summarized: "He measures recent erosion, applies a linear model, and gets that figure, which is essentially pulled out of thin air."
The Impossible Technological Leap
Beyond the numbers, the underlying debate concerns how a Neolithic civilization could transition from building mud-brick mastabas to erecting limestone monuments with 2.3 million blocks and millimeter tolerances in just a couple of centuries. Some argue for lost prior knowledge; others maintain that the evolution from mastabas to the Giza pyramids is documented and requires no extraterrestrial intervention or earlier civilizations. Snefru’s Bent Pyramid, with its angle change, is often cited as an experiment demonstrating learning through trial and error.
Donini’s study will not rewrite history books, but it forces us to question the reliability of our dating techniques when applied to stone. While carbon-14 is ineffective here and thermoluminescence yields ranges of 28,000 years, the Great Pyramid continues to keep its secrets. The lingering question is whether we truly know when it was built, or if we are merely projecting our technical limitations onto the past.
