Dr. Zahi Hawass on the Joe Rogan Experience #2321, fact-checked

What the evidence shows: Three of the four textbook figures Hawass cites match mainstream Egyptology. The fine white limestone casing of the Great Pyramid did come from the Tura quarries, and the commonly cited estimate of about 2.3 million stone blocks is standard (National Geographic notes roughly 2.3 million blocks and the Tura casing source). The 23-year reign for Khufu is the figure preserved in the Turin Royal Canon and widely used, though ancient sources disagree (Herodotus gives 50 years, Manetho 63). The distance is where Hawass is imprecise: Tura sits on the east bank of the Nile southeast of Giza, roughly 8 to 15 km away, described by Smithsonian as about 12 miles south of Cairo, not 25 miles due east. Overall the characterization is accurate as a summary of textbook claims, with the Tura distance and direction overstated.

What the evidence shows: A cemetery of the workers who built the Giza pyramids was documented in 1990 to the south of the Sphinx, and Zahi Hawass led its excavation. Smithsonian reports the site sits about half a mile south of the Sphinx (not one mile) and that it came to light after an American tourist's horse stumbled on a mud-brick wall, after which Hawass investigated. The roughly 600 tombs include overseers' graves with inscriptions recording their names and titles, and the fact that laborers were buried in prepared tombs beside the king's pyramid is cited as evidence they were paid Egyptian workers, not slaves. The core claim (Egyptian-built pyramids shown by named tombs of the builders found south of the Sphinx) is supported; the stated distance is overstated and the framing as a solo find omits the accidental discovery, so the claim is largely accurate.

What the evidence shows: Excavations of the Giza workers' town led by Mark Lehner and Zahi Hawass recovered large quantities of cattle, sheep, and goat bone showing the builders ate a protein-rich, meat-heavy diet, and the layout of the barracks and cemetery indicates organized, paid, rotating labor rather than slaves. National Geographic reports the settlement had a maximum capacity of roughly 20,000 people, of whom perhaps half were dedicated to construction at any one time, which is consistent with Hawass's estimate of about 10,000 builders. The Smithsonian account of the site notes that the diet, including prime beef from young male cattle, indicates the workers were not slaves. The precise daily provisioning figure (11 cows and 33 goats) is Hawass's own published estimate derived from the faunal remains rather than an independently confirmed daily headcount, so it is best read as an illustrative order-of-magnitude figure. The broad picture, a well-fed workforce on the order of 10,000 organized laborers, is well supported: largely accurate.

What the evidence shows: There is no single fixed count of Egyptian pyramids because the total depends on classification (whether ruined mud-brick structures and smaller queens' or secondary pyramids are counted) and because new structures are still being identified. Published tallies commonly range from at least 118 to about 138 identified pyramids, and some sources cite roughly 120. The Smithsonian notes there are more than 100 pyramids in Egypt, with the Giza group (Khufu, Khafre, Menkaure) being only the most famous. Hawass's figure of 120 falls within the accepted range and correctly conveys that Egypt has far more than the single Khufu pyramid, though it should be read as an approximation rather than a precise total.

What the evidence shows: The core claim is correct: the Wadi al-Jarf Papyri (including the Diary of Merer) are the oldest inscribed papyri ever found and are the first contemporary written record connected to building the Great Pyramid of Khufu. However, the timeframe is off. A French-Egyptian mission led by Pierre Tallet discovered the papyri in 2013 (the first fragments found March 24, 2013, with the main cache days later), not three years before this 2025 episode. Relative to the episode, the discovery was roughly twelve years earlier, so Hawass's 'three years ago' figure is substantially inaccurate even though the identification of the find is sound.

What the evidence shows: The Wadi al-Jarf papyri (also called the Diary of Merer or Red Sea Scrolls), discovered by Pierre Tallet's French-Egyptian mission between 2011 and 2013, are the oldest inscribed papyri ever found. They are internally dated to the reign of Pharaoh Khufu of the Fourth Dynasty, with the latest documents recording the 27th year of his reign, placing them in the mid-26th century BCE (roughly 2560s BCE). That is approximately 4,600 years before the present, matching Hawass's figure. Smithsonian's coverage explicitly describes the site and papyri as dating to about 4,600 years ago.

What the evidence shows: The Wadi al-Jarf papyri (the Diary of Merer) are dated to the year after the 13th cattle count of Khufu, which excavator Pierre Tallet describes as the latest attested date of the reign, corresponding to roughly the 27th regnal year. Tallet states the papyri give the last date we have for Khufu, the 27th year of his reign, so they establish a minimum rather than a fixed total. Egyptologists remain divided because the older Turin Canon assigns Khufu only 23 years, and interpretation depends on whether the cattle counts were biennial, with estimates ranging from about 27 years upward. The claim that a 28-year reign is now known for sure overstates the evidence: the papyri support a reign of at least about 27 years, but the exact length is not settled.

What the evidence shows: The long-standing textbook estimate for the Great Pyramid is roughly 2.3 million stone blocks, a figure cited by National Geographic, Smithsonian, and a 2025 peer-reviewed study in npj Heritage Science. Hawass's stated figure of only more than one million is far below that consensus and reflects his own argument that the pyramid's base incorporates a large natural bedrock knoll (reported as about 20 feet high), which would reduce the count of quarried blocks; this remains his revision rather than an established replacement for the 2.3 million estimate. On the weights, standard sources put the average block near 2.5 tons, with upper-course limestone blocks around 1.3 tons and base and granite stones far heavier, so Hawass's half a ton to two and a half tons range is broadly consistent for the ordinary limestone blocks though it omits the heaviest stones. Overall the weight range is defensible while the more than one million block count is a disputed, lower-than-consensus figure specific to Hawass's own recount.

What the evidence shows: It is well established that the Great Pyramid was not built entirely from stacked quarried blocks: its lower core incorporates a natural bedrock knoll left in place when the builders leveled the surrounding plateau, and the commonly cited 2.3 million block figure is a whole-volume approximation that does not subtract this rock core. However, a 2026 peer-reviewed study in Nature (npj Heritage Science) puts the bedrock knoll at on the order of tens of percent of the lower core, spanning roughly the first 17 courses of masonry, and stresses that its exact size cannot be measured because it is fully enclosed. Removing about 1,300,000 stones would mean the natural core replaces more than half of the roughly 2.3 million total blocks, which is far larger than any current scholarly estimate. So the underlying point (that a solid rock core lowers the true block count) is real, but the specific 1.3 million figure is unsupported and substantially exaggerated relative to the published evidence.

What the evidence shows: The core biographical claim checks out. The National Geographic Society named Zahi Hawass an Explorer-in-Residence in 2001 (Hawass says 2000), an honor he shared with figures such as Jane Goodall, James Cameron, and paleontologists Meave and Louise Leakey. Robert Ballard (the guest garbles the name as Bill Billard), who discovered the wreck of the RMS Titanic in 1985, is also a longstanding National Geographic Explorer-in-Residence, so the two held the same title. The specific figure of nine explorers is not precisely documented in the sources reviewed, and the year is off by roughly one, but the substance of the claim (Hawass and the Titanic discoverer both being National Geographic Explorers-in-Residence) is correct.

What the evidence shows: It is well established that Hatshepsut, one of Egypt's few female pharaohs, was subject to a posthumous campaign of erasure: her successor Thutmose III had her images defaced, her statues broken, her name chiseled from monuments, and her rule removed from official king lists. On that core fact Hawass is correct. His stated motive, that a pharaoh could not be female and so she was struck down for it, is the older popular narrative that modern Egyptology largely qualifies or rejects. The erasure did not begin until roughly two decades after Hatshepsut's death, which undercuts a simple gender or revenge explanation, and specialists now emphasize political and dynastic aims such as securing a clean line of male succession from Thutmose I through III to Amenhotep II. A 2025 study in Antiquity by Jun Yi Wong further argues that much of the statue damage reflects routine ritual deactivation and later reuse rather than targeted destruction, though scholars agree a real proscription campaign occurred and its precise motive remains debated. In short, the destruction is real but framing it as simply because she was female overstates a contested point.

What the evidence shows: The March 2025 Giza claims came from Corrado Malanga (a retired organic chemist from the University of Pisa) and Filippo Biondi (a remote sensing expert associated with the University of Strathclyde), working with Armando Mei under the Khafre Project. Their analysis relied on synthetic aperture radar (SAR) data collected by satellite, not on-site excavation or fieldwork inside the pyramids, which matches Hawass's point that they never worked at the site. The sensational 2025 underground-city claims were announced via a press briefing and press release and were not peer-reviewed or published in a scientific journal, a point echoed by National Geographic and multiple independent experts. Hawass's framing is imprecise on one point: an earlier 2022 paper by the same authors on the Khafre pyramid's internal structure was published and peer-reviewed in the journal Remote Sensing, so it is the specific 2025 claims, not all of their output, that lack peer review. Radar experts also note that SAR typically penetrates only a couple of meters, making the deep-structure interpretations a substantial exaggeration.

What the evidence shows: Drilling and geophysical work around the Sphinx are documented: the Smithsonian reports that Hawass had workers drill test holes in the bedrock (finding the water table only about 15 feet down) as part of groundwater and conservation efforts, and earlier boreholes were placed on geophysical anomalies. However, the claim that there is nothing underneath overstates the certainty of the record. A peer reviewed seismic survey published in Geoarchaeology (Dobecki and Schoch, 1992) defined a series of subsurface cavities on each side of the Sphinx as well as between its paws, and buried bedrock structures in the adjacent desert. Mainstream archaeologists interpret these features as natural fissures and weathering rather than man made chambers, so no hidden room has been confirmed, but published data do show voids and cavities in the rock, which contradicts a flat statement that the bedrock is solid with nothing beneath it. The drilling itself was limited to a small number of boreholes rather than exhaustive coverage everywhere.

What the evidence shows: The geologist Hawass refers to is K. Lal Gauri, whose peer-reviewed work argued against Robert Schoch's claim that the Sphinx is thousands of years older based on ancient rainfall, and it did support a conventional pharaonic date. But Gauri and the mainstream account do not conclude the erosion is from wind and not water: the leading explanation, described by Egyptologist Mark Lehner, is that intermittent wet periods dissolved salts in the limestone, which recrystallized and caused softer stone to crumble, with wind then blowing away the loosened flakes (Smithsonian). Moisture, whether from dew, groundwater, or wet-dry climate cycles, is central to this salt-crystallization mechanism, so wind alone is not the cause. Separate research shows wind erosion can shape natural sphinx-like landforms (yardangs) that humans may later have carved, but that too works alongside water and rock composition, not instead of water (Science News). Framing the mainstream position as wind and not water oversimplifies it: what geologists actually reject is Schoch's prolonged prehistoric rainfall and early dating, not the role of water or moisture in the weathering. This claim is misleading.

What the evidence shows: The claim that radiocarbon dating has never given accurate results and does not work in Egypt is contradicted by peer-reviewed research. The 2010 Science study by Bronk Ramsey and colleagues used 211 radiocarbon measurements on short-lived plant remains with Bayesian modeling and independently corroborated the historically derived Egyptian chronology, reducing some uncertainties to under 20 years. A 2013 Proceedings of the Royal Society A study likewise produced an absolute radiocarbon chronology for early Egypt that, in the authors' words, concurs with prevailing archaeological analysis. There is a real caveat: earlier pyramid radiocarbon projects (1984 and 1995), on which Hawass was a co-author, found dates that ran several hundred years too old, but researchers attributed this to the old wood problem (builders reusing aged organic material) and a small Nile Valley growing-season offset, not to any failure of the method itself. When short-lived samples from secure contexts are used, radiocarbon dating agrees well with Egyptian chronology, so the blanket claim that it never works is inaccurate.

What the evidence shows: In April 2021 an Egyptian mission led by Zahi Hawass announced the discovery of a large, well-preserved city near Luxor on the Nile's west bank, named the Rise of Aten and dating to the reign of Amenhotep III (roughly 1391 to 1353 BC). National Geographic and Smithsonian both attribute the find to Hawass and describe it as one of the most significant Egyptian archaeological finds in a century, with experts calling it the second most important discovery since Tutankhamun's tomb and comparing its preservation to an Egyptian Pompeii. Hawass's characterization of it as the first large city revealing the daily lives of the people of this era is consistent with how specialists framed its value. His phrase 'most important discovery in the world of year 2021' refers specifically to a top-discovery designation by Archaeology Magazine in December 2021, so the ranking is a magazine editorial pick rather than a universal ranking, but the underlying discovery and its scale and attribution are accurate.

What the evidence shows: Radiocarbon dating of the Great Pyramid did rely on organic material (ash and charcoal from fires used to prepare the gypsum mortar) that was extracted from mortar between the blocks, as the on-air claim describes. Egyptologists place Khufu's reign and the pyramid's construction in Dynasty 4 around 2528 BC (Harvard's Digital Giza, citing the study titled The Great Pyramid of Giza in the Year 2528 B.C.), consistent with the roughly 2500 BC figure cited. The mortar radiocarbon program run by Bonani, Lehner, Hawass and colleagues (1984 and 1994 to 1995) produced a wide scatter, with many calibrated dates running one to three centuries older than the historical age; the offset is attributed mainly to the old wood effect, and the youngest samples still align with the conventional Khufu date. So the substance of Rogan's statement (organic material in the mortar was carbon dated, placing the pyramid near 2500 BC) holds up: roughly accurate.

What the evidence shows: The Dream Stela is a pink granite slab located between the paws of the Great Sphinx at Giza, erected by Thutmose IV of the 18th Dynasty. According to the Smithsonian, the inscription recounts that the prince Thutmose grew tired while in the desert and lay down in the shade of the Sphinx, whereupon the statue (identifying itself as the god Horemakhet) spoke to him in a dream, complained about the accumulating sand, and offered him the throne in exchange for clearing it away. The Smithsonian Learning Lab likewise catalogs the monument as the Dream Stela standing between the Great Sphinx's forepaws at Giza. Hawass's account of the stele's location and its sand-for-kingship dream narrative matches the mainstream Egyptological record: Accurate.

What the evidence shows: Herodotus devotes much of Book II of the Histories to Egypt, including detailed descriptions of the Giza pyramids, yet never mentions the Great Sphinx, an omission scholars describe as astonishing. Hawass's explanation, that the Sphinx was buried in sand and therefore not visible, is a leading account: the monument was repeatedly engulfed by desert sand, documented from the Dream Stele of Thutmose IV (around 1400 BC) through its 1818 and 1926 excavations, and one review notes it was largely buried in sand around Herodotus's time. That said, the buried-in-sand reason is one hypothesis rather than settled fact, and other scholars attribute the silence to Herodotus's limited interest in such statuary or to doubts about how much he saw firsthand. The core claim that Herodotus never mentioned the Sphinx is correct; the stated reason is a plausible but debated explanation.

What the evidence shows: Gobekli Tepe is a Pre-Pottery Neolithic archaeological site in southeastern Turkey, about 12 km northeast of the city of Sanliurfa, per peer-reviewed research in PLOS ONE. That research dates the monumental structures to roughly 11,500 to 10,000 years before present, consistent with the claim of more than 11,000 years old. The site is famous for its massive carved T-shaped pillars and circular stone enclosures, which the Smithsonian notes predate Stonehenge by some 6,000 years and were built before metal tools or pottery. The claim's location, age, and description as complex stone structures are all supported by the sources.

What the evidence shows: Djoser's Step Pyramid at Saqqara, designed by Imhotep, is the earliest large-scale Egyptian pyramid and is dated to the Third Dynasty, roughly 2670 to 2630 BCE. Khufu's Great Pyramid at Giza was built in the Fourth Dynasty, generally dated to about 2560 to 2550 BCE. National Geographic places the Step Pyramid at around 2780 BCE and Khufu's project at about 2550 BCE, an interval of roughly 230 years, while mainstream chronologies that put Djoser closer to 2630 to 2670 BCE yield a gap of only about 70 to 130 years. No standard chronology supports a separation of nearly 700 years, so the roughly 700-year figure is a substantial exaggeration.

What the evidence shows: The pyramid-building sequence Hawass describes matches Egyptology consensus. Sneferu (first king of the 4th Dynasty, c. 2613 to 2589 BC) built at Meidum, where a step pyramid was begun and later reworked toward a smooth-sided form, before turning to Dahshur. There he built the Bent Pyramid, whose lower section rises at about 54 degrees while the upper part shifts to roughly 43 degrees, a mid-construction change in angle that gives the monument its bent profile. His subsequent Red Pyramid at Dahshur, built at the shallower 43-degree angle, is regarded as the first successful true (smooth-sided) pyramid. The account of a Meidum start followed by the angle-changed Bent Pyramid at Dahshur is accurate.
