The researchers claim to have discovered eight vertical cylinder-shaped structures, referred to as shafts, extending approximately 2,100 feet deep beneath the pyramids.
Italian and Scottish researchers claim they found a major discovery beneath the Pyramids of Giza, potentially rewriting the history of ancient Egypt. Using radar technology, the team led by Corrado Malanga from Italy's University of Pisa and Filippo Biondi from the University of Strathclyde in Scotland announced the findings of what they describe as a vast underground city stretching more than 6,500 feet directly beneath the pyramids.
There is no way in that era and frankly not in our era that you could go that deep beneath the surface of the earth.
and at that depth the temperature would be over 150 degrees F
So either this is a complete hoax or they have found evidence that Aliens built themselves a city down there
I should say that you could not build a city that deep. We have a mine in South Africa that goes down about three times that deep; and its so hot they have to have extreme air conditioning to survive.
