The ancient archaeological site is located on the outskirts of Cairo, Egypt, and includes three pyramidsand the Great Sphinx.
The Khufu, Khafre and Menkaure can all be found in the Western Desert, approximately 9km (5.5 miles)from the Nile river.
Listed as one of the Seven Wonders of the World, the huge structures date back to roughly 2,570BC, according to the history books.
But new evidence could prove they were in fact created 5,000 years earlier, according to historian Matt Sibson.
“if you look at one corner in the southwest, it looks like it has been plastered over with clay”
“If you look at the second pyramid, not the Great Pyramid, but the pyramid of Khafre – it has a wall around it,” he told Daily Star Online exclusively.
“The wall looks flat and natural, but if you look at one corner in the southwest, it looks like it has been plastered over with clay.
“And where the smooth finish dies away, you’re left with a very, very weathered wall.
“The wall is part of the pyramid’s foundation, it is the first thing cut, so we know that had to have happened first.
“So it looks like the wall was very weathered before they started constructing the actual pyramid years later –plastering clay over the top.”
And Matt, from Leicester, believes an ancient civilisation may have finished off work started thousands of years earlier.
He revealed to Daily Star Online: “We can see rain erosion on the wall, but geologists say there was no rain heavy enough to cause such damage at the time (2,570BC).
“It was around 5,500 years earlier – roughly 8,000BC – where the rain matched that needed for the erosion.”
The 36-year-old researcher shared his incredible finding with his 165,000 strong fanbase on his YouTube channel.
And some were stunned.
“I agree with everything you put forward, I wish mainstream archaeologists would listen to these theories,” one viewer wrote.
Another added: “The Pyramids of Giza are the most radical examples of ‘Modernist’ architecture.
“They look more like something you might expect to find on a day trip to Mars.”
And a third claimed: “Thanks to your research we are getting closer to the truth.
