Scientists believe they may have solved the mystery of how 31 pyramids, including the world-famous Giza complex, were built in Egypt more than 4,000 years ago. Surprisingly, it wasn’t aliens.

A research team from the University of North Carolina Wilmington has discovered that the pyramids are likely to have been built along a long-lost, ancient branch of the River Nile – which is now hidden under desert and farmland.

For many years, archaeologists thought that ancient Egyptians must have used a nearby waterway to transport materials such as the stone blocks needed to build the pyramids on the river, but up until now, nobody was certain of the location, the shape, the size or proximity of this mega waterway to the site of the actual pyramids.

Researchers used radar satellite imagery, historical maps, geophysical surveys, and sediment coring (a technique used by archaeologists to recover evidence from samples) to map the river branch – which they believe was buried by a major drought and sandstorms thousands of years ago.

The team were able to “penetrate the sand surface and produce images of hidden features” by using radar technology, the study, published in the journal Nature, said.

Among those features were “buried rivers and ancient structures” running at the foothills of where the “vast majority of the Ancient Egyptian pyramids lie,” Prof Ghoneim said.

“Locating the actual [river] branch and having the data that shows there was a waterway that could be used for the transportation of heavier blocks, equipment, people, everything, really helps us explain pyramid construction”.

The team found that the river branch – named the Ahramat branch, with “ahramat” meaning pyramids in Arabic – was roughly 64km long and between 200-700 metres wide. And it bordered 31 pyramids, which were built between 4,700 and 3,700 years ago.

The discovery of this extinct river branch helps explain the high pyramid density between Giza and Lisht (the site of Middle Kingdom burials), in what is now an inhospitable area of the Saharan desert.

The river branch’s proximity to the pyramid complexes suggests that it was “active and operational during the construction phase of these pyramids”, the paper said.

Dr Onstine explained that ancient Egyptians could “use the river’s energy to carry these heavy blocks, rather than human labour,” adding, “It’s just a lot less effort”. But it didn’t hurt to have an endless supply of slave labour to throw at the pyramids either.

Once again, science spoils pseudoarchaeology’s belief that extraterrestrials helped the ancient Egyptians build the pyramids.

I still prefer the alien angle though, just like the famed scholar and Director of von Daniken’s Ancient Alien Society Giorgio Tsoukalos.
