Ancient CivilizationsAnother Egyptian Giza pyramid bombshell as new ‘evidence’ on underground city discovery that ‘reshapes history’ Posted on April 9, 2025 by Administrator A new development in the mystery of a purported city beneath Egypt’s Giza pyramids could, if proven true, fundamentally reshape our understanding of human history. Italian researchers told DailyMail.com that not only are the shafts and chambers they found deep below the Khafre pyramid 38,000 years old, but also the Giza complex. The Giza complex, consisting of the Khufu, Khafre and Menkaure pyramids, is widely believed to have been constructed around 4,500 years ago.
