Antonio Ambrosio, a researcher from the Autonomous University of Barcelona, has proposed a bold theory suggesting the Great Pyramids of Giza were not erected by ancient Egyptians. Instead, he posits they were built by a far more advanced civilization that flourished approximately 12,000 years ago. In his recent paper, which has yet to undergo peer review, the scholar presents several arguments indicating the Egyptians simply claimed credit for these grand structures after finding them already complete, as reported by the Daily Mail.
Ambrosio highlights the striking absence of pharaonic mummies or funerary artifacts inside the Giza pyramids, despite these monuments officially being attributed as the tombs of Khufu, Khafre, and Menkaure. The scientist emphasizes the unparalleled engineering prowess of the pyramids’ creators: their precise alignment to the cardinal points, the meticulous fitting of stone blocks, and the leveling of the foundations. In his view, these feats were never replicated in the construction of succeeding, smaller pyramids built between 2500 and 2150 BCE, which frequently exhibited structural flaws.
Furthermore, the investigator points to evidence of water erosion marks on the Sphinx statue and the base of the pyramids, features attributable only to heavy rainfall. Climatic data confirms that such intense precipitation ceased in Egypt around 3000 to 5000 years BCE. This suggests that the Giza complex was already in place and subject to elemental weathering long before the Egyptian civilization reached its zenith.
Antonio Ambrosio argues that the Giza pyramids are the legacy of an unknown, highly sophisticated culture possessing technologies now lost to humanity. To buttress his hypothesis, he cites examples of other megalithic sites globally, such as Sacsayhuamán in Peru and Baalbek in Lebanon, which share comparable construction characteristics. The scholar speculates that this “super-civilization” might have existed during the era the Egyptians themselves referred to as “Zep Tepi” or the “First Time”—a golden age when deities reigned upon Earth.
Certain researchers, including Graham Hancock and Robert Schoch, also endorse the concept of an advanced precursor civilization dating back to around 10,500 BCE. Another independent researcher, Matthew LaCroix, posits that this ancient culture might have embedded its knowledge within the geometry and symbolism of monuments worldwide, intending to preserve it against forthcoming global catastrophes. He draws attention to recurring symbols and architectural motifs discovered across different continents, whose age could potentially stretch back 40,000 years.
