Shocking Discovery Claims Great Pyramid of Giza May Be 20,000 Years Older—Rewriting History as We Know It!
So, imagine this: what if the Great Pyramid of Giza isn’t just a flashy 4,500-year-old relic, but actually a whopping 25,000 years old? Yeah, you heard that right — 20,000 years older than we’ve been taught in every school history book ever! Alberto Donini, some brainy engineer from the University of Bologna, stirred the pot with a funky new technique he calls the “Relative Erosion Method” (REM). By eyeballing how much weathering has chipped away at the stones, he reckons this colossal monument might have been built around 23,000 B.C.E. Now, before you start picturing ancient Egyptians with stone rollers and caveman tech, this claim throws a huge wrench into the accepted story — and, honestly, it’s making me question everything I thought I knew about Egypt! Could this be a game-changer or just another wild archaeological hiccup? Buckle up, because the sands of time are shifting under our feet.
A new method that compares points of erosion on the Great Pyramid of Giza suggests that this iconic monument could have been constructed as early as 23000 B.C.E. — 20,000 years earlier than previously believed.

The Great Pyramid of Giza, generally believed to have been built as the tomb of Pharaoh Khufu around 2575 B.C.E., is one of the Seven Wonders of the Ancient World. But what if it’s even older than that?
Alberto Donini, an engineer from the University of Bologna, recently applied a new dating system that he calls the “Relative Erosion Method” (REM) to the pyramid. Now, he’s claiming that his research suggests the famous landmark may have actually been built nearly 25,000 years ago.
When Was The Great Pyramid Of Giza Built? The Origins Of Egypt’s Ancient Wonder
Scientific studies of the pyramids at Giza have been ongoing for centuries, so the current timeline of their construction is widely accepted. As it stands, the Great Pyramid was seemingly built during the reign of Pharaoh Khufu, who ruled over Egypt from roughly 2589 B.C.E. to 2566 B.C.E. The Pyramid of Khafre came shortly thereafter, followed by the Pyramid of Menkaure.
This timeline was determined using both historical records and scientific study. Ancient authors like Herodotus wrote that Khufu had the Great Pyramid constructed as his tomb, noting that he “brought the people to utter misery” by making them transport impossibly heavy limestone blocks from quarries — possibly located hundreds of miles away — in order to erect the 481-foot structure. Exactly how they managed this remains a mystery to this day, though several promising theories have been put forth, such as the use of a ramp system.

Then, in the 1800s, archaeologists discovered graffiti inside the Great Pyramid that mentioned Khufu by name. It was seemingly scrawled by the workers who built the monument, adding another layer of evidence that the structure was built during that pharaoh’s reign.
Archaeologists later used scientific methods to date the pyramid. They radiocarbon dated the mortar used to secure the stone blocks, which was made using ashes and thus contained organic matter. These results suggested that the mortar was likely mixed between 2620 and 2484 B.C.E., once again aligning with the reign of Khufu.
With so much proof pointing to a construction date of roughly 2575 B.C.E., it seems unlikely that there’s any additional information out there that could significantly change the timeline. However, Alberto Donini claims that his research could completely rewrite this story.
Why The Relative Erosion Method Could Complicate The Story Of How Old The Great Pyramid Of Giza Is
In a preliminary report on his research, Alberto Donini describes his new “Relative Erosion” dating method: “The REM is based on the ratio between two types of erosion affecting the same type of rock in the same location: one with a known date and the other with a date to be determined. The ratio is then used to calculate the age of the stone block under examination.”
When the pyramids of Giza were built, they were covered in a gleaming casing of smooth, polished, white limestone. Then, in 1303, a massive earthquake struck the region, knocking some of these stones to the ground. The fallen material was recycled to build palaces and mosques in Cairo, and in the years that followed, even more of the limestone was removed intentionally to use for decorative purposes. By 1400, much of it was gone.

Donini began his research by comparing the areas of the Great Pyramid that were once covered by limestone with stones at the structure’s base that have always been exposed to the elements. By comparing the amount of erosion that’s taken place in the past seven centuries to the amount of erosion on the blocks that were never covered by limestone, Donini believed he could calculate when those original stones were placed.
