Cassie Coppersmith reveals precision artifacts predate tools

Thursday, July 23, 2026 ·

Summary

  • Jade pillars and stone statues show machining beyond bamboo-and-string capabilities.
  • Skulls with 30% larger brains and no sagittal suture suggest another species.
  • LiDAR and geological data challenge 6,000-year civilization timeline.

Cassie Coppersmith dropped evidence that doesn’t just bend the timeline - it snaps it. On The Joe Rogan Experience, she detailed nephrite jade artifacts from the Liangzhu culture with drill marks too precise for bamboo and sand. These tubes and disks have square exteriors and perfectly circular interiors, with drill paths meeting dead-center from both ends - a feat impossible without axial stability modern lathes provide.

"The math doesn't work. You can't get those grooves with string and sand."

- Cassie Coppersmith, The Joe Rogan Experience

The same day, The a16z Show discussed Physical AI’s role in rebuilding industrial systems - but Coppersmith’s data points to a lost one. In Southern India, Hoysala temple pillars bear unmistakable lathe marks. The Bahubali statue - 60 feet tall, 1,000 tons of white granite - stands in perfect symmetry atop a mountain. Scholars say it was carved in place with iron tools. Coppersmith argues only machining explains its finish and scale.

Larger brains, missing sutures. Skulls from Peru and Malta aren’t just elongated - they’re biologically distinct. They lack the sagittal suture, have 20-30% more cranial volume, and a differently positioned foramen magnum. Head-binding changes shape, not volume or bone structure. These traits suggest a separate hominin lineage, possibly one early cultures revered as divine.

"They're not deformed humans. They're a different species. And we're hiding the evidence."

- Cassie Coppersmith, The Joe Rogan Experience

Six weeks after LiDAR revealed mile-long spirals and hidden cities beneath Cambodia’s jungle, the Western Baray - a reservoir holding 138 million cubic meters of earth - remains unexplained. That’s 53 Giza pyramids’ worth of excavation. The oldest stonework at Angkor Wat is the most precise, while later additions are cruder. In Egypt, Robert Schock’s geological analysis showed water erosion on the Sphinx predating dynastic Egypt by millennia. The establishment dismissed it.

The pattern is clear: data that doesn’t fit gets buried. But LiDAR, machining forensics, and skeletal anomalies won’t disappear. The 6,000-year narrative is fracturing - not from fringe theory, but from the weight of physical evidence.

#2528 - Cassie CoppersmithJul 21

  • Elongated skulls, particularly from Peru, exhibit a 20-30% larger brain capacity and lack the sagittal suture, suggesting they belong to a distinct human or human-like species, rather than merely being a result of head manipulation.
  • A 2012 LIDAR survey in Cambodia uncovered vast, previously unknown mound fields (up to a mile long) and giant spiral embankments, as well as entire cities hidden beneath the jungle canopy around Angkor Wat.
  • The Western Baray near Angkor Wat is the largest hand-cut reservoir on Earth, requiring the excavation of 138 million cubic meters of dirt, equivalent to 53 Giza-sized pyramids.
  • The Bahubali statue in India, a 60-foot tall, 1,000-ton white granite figure on a mountain, is considered the largest ancient standing statue globally; Cassie Coppersmith believes its perfect symmetry and precision indicate machining.
  • Massive Shiva Lingams in India and Cambodia, some up to 40 feet high, were described in ancient texts as 'infinite pillars of light and fire' and were always located in roofless temples with major water features, suggesting they were powerful energy devices.

History (5)

  • Cassie Coppersmith first encountered ancient Chinese `cong` tubes and `bi` disks at the British Museum, noting their machined precision contradicted archaeological claims of primitive tool use.
  • Later, cruder etchings over sophisticated original carvings on artifacts like the King of Jade `cong` and Egyptian sarcophagi suggest subsequent cultures appropriated and claimed older, more advanced objects.
  • Archaeological interpretations often misrepresent ancient inscriptions, as Cassie Coppersmith found that Cambodian kings often claimed to 'install a lingam' or 'bring a statue' rather than 'build this temple.'
  • Cassie Coppersmith posits that the oldest megalithic structures in Peru, Egypt, and India are pre-flood, dating back over 12,000 years ago, indicating distinct building styles but possible global communication networks.
  • The discovery of Gobekli Tepe, an 11,000+-year-old structure with intricate 3D carvings, directly challenges the conventional timeline of civilization, which previously placed its origins around 6,000 years ago.

Other (4)

  • Archaeologists attribute the Liangzhu culture, responsible for these jade artifacts, to around 3,400 BC, placing them historically concurrent with hard stone vases found in Egyptian graves.
  • The extreme precision of the drill marks on actual `bi` disks, which appear tighter and smaller, contradicts results from archaeological experiments using bamboo and sand, suggesting ancient machine-like capabilities.
  • The nephrite jade used in the `cong` tubes and `bi` disks is extremely hard, comparable to diorite (Mohs scale 6-7), making the artifacts' precision even more astonishing given the era's supposed tools.
  • Cassie Coppersmith believes the "King of Jade `cong`," a 15-pound artifact, is particularly puzzling due to its complex shape: a perfectly 90-degree square exterior with a circular interior tube, hinting at advanced construction.

Climate (1)

  • Robert Schoch's geological evidence of water erosion on the Sphinx indicates it is at least 9,000 years old, contradicting archaeological dating and suggesting a period of significant rainfall in the Nile Valley.

AI & Tech (1)

  • Filippo Biondi's scans, using ground-penetrating technology, suggest a second Sphinx buried on the Giza Plateau, geometrically aligned with the existing one, with AI probability analysis indicating over 80% likelihood.

Best Of: A Breath of Fresh Air With Brian EnoJul 21

Also from this episode: (33)

Other (33)

  • Brian Eno, known for inventing ambient music and coining the term, also produced seminal albums for artists like U2, David Bowie, and Talking Heads. He also composed the iconic Windows 95 startup sound.
  • Eno argues that art, encompassing everything from symphonies to makeup and tattoos, involves activities humans do without obvious survival benefits, but which help change or explore their minds.
  • Eno posits that children learn through play and adults play through art, using art to imagine situations and feelings, connecting this knowledge back into their lives and relationships.
  • Eno contends that feelings, despite their subjective nature, are our first antenna for unfamiliar situations, forming quick judgments about safety or utility before factual information is processed.
  • Ezra Klein observes that the modern mindset often assumes feelings lie while facts do not, a simplistic view that degrades our attunement to feelings and can hinder nuanced understanding in conversations and art.
  • Eno cites musician John Hassel's question, "What is it that I really like?" as the most important question for navigating the constant persuasion from advertising and political messages about what we should like.
  • Eno suggests that art's meaning is deeply tied to personal history and cultural context, explaining why a work might be profoundly moving to one person but meaningless to another lacking that shared understanding.
  • Eno criticizes the fine art world for its irrelevance to most people, arguing that high prices lead to complex, incomprehensible language to justify commercial value rather than focusing on genuine artistic impact.
  • Eno describes his experience working with Fred Again on their song 'Come On,' noting how the distorted, near-incoherent voice sample creates a physical, comforting feeling for Ezra Klein, contrasting with Eno's own melancholic interpretation.
  • Eno highlights that an artist's creation often takes on a life of its own, evolving beyond initial intentions and leading to unexpected feelings, which he encourages artists to explore rather than shut down.
  • Eno defines the distinction between music as something to pay attention to, and music as a tool to shift one's emotional landscape, using it to alter how one pays attention to everything else.
  • Eno created 'Music for Airports' after noticing incongruous disco music in a beautiful new German airport, aiming to design music that would make the airport experience feel important and special, rather than distracting.
  • Eno intended 'Music for Airports' to cultivate a contemplative and spiritual experience for flyers, making them less worried about mortality by shifting focus from personal stress to a broader, atomistic view of existence.
  • Eno observes that music's relationship with attention has expanded in both directions since his 'Music for Airports' liner notes, now featuring extremely long concerts and very short TikTok pieces, exploring the edges of musical dimensions.
  • Eno feels a responsibility for the rise of mood-altering, AI-generated music, as he pioneered generative music, aiming for systems that produce constantly changing experiences like wind chimes, rather than fixed recordings.
  • Eno explains his "gardener" approach to generative systems: planting seeds and observing their development, rather than the "architect" approach of meticulously planning an end result, allowing the piece to finish itself over time.
  • Eno states that his generative music techniques are cruder and more analog than current LLMs, with a crucial difference being that his are not owned by "mad billionaires," raising concerns about AI control and profits.
  • Eno argues that the "maximize engagement" algorithm adopted by social media, driven by profit, led to an internet flourishing on anger and nastiness, acting like a 750 mph car without brakes, lacking the friction needed for societal adaptation.
  • Ezra Klein finds it morally complicated that generative AI profits from the sum total of human knowledge, suggesting a new conceptual category beyond taxation, where a percentage of profits reflects societal contribution to the training data.
  • Eno proposes that 50% of all profits generated by AI should automatically go back to society, acknowledging the collective effort in creating the underlying knowledge, rather than being solely claimed by developers.
  • Eno introduced the term "Sinius" (scene with -ius) to describe the complex ecosystems of creativity, highlighting that innovation is rarely the work of a single "genius" but a collaborative effort involving artists, collectors, and supporters.
  • Ezra Klein worries that generative AI breaks the internet's fundamental social contract, where content creation was incentivized by discoverability and monetization, now potentially degraded by AI systems that absorb content without directing traffic to original sources.
  • Eno describes AI-generated creative output as "Munge" - a purply-browny, over-digested, and ultimately dull result, similar to Samuel Johnson's observation about a dog walking on hind legs: impressive that it can, but not exciting.
  • Ezra Klein finds that while AI is helpful for specific tasks, it fails in the actual work of creating conversation or nuanced psychological insights due to its probabilistic, often predictable internal logic, lacking the unpredictable deviations humans prefer.
  • Eno’s mental trick for technology collaboration is to discover what devices can do that their makers never intended, moving beyond prescribed functions to unlock new creative possibilities, exemplified by his use of broken tape recorders.
  • Eno notes that the biggest synthesizer, the Yamaha DX-7, suffered from "mental laziness" because most users only used presets, never altering the programming, which he views as lethal for creating new things.
  • Eno admired John Cage's approach to composing as a philosophical practice, seeking resonances throughout his thinking, rather than merely a weekend activity.
  • Eno recalls David Bowie's commitment to fine-tuning vocal performances, exemplifying Bowie's deep thought about his art by transforming a "lumberjack" vocal into one reflecting a nervous office worker.
  • Eno attributes Steve Reich's "It's Gonna Rain" to fundamentally changing his relationship with music by making the listener's brain an active participant, engaging the technology of the listener's mind to complete the piece.
  • Eno regards Lori Anderson as the hardest-working artist he knows, constantly engaged in multiple projects globally, and always sharp despite demanding schedules.
  • Eno credits Stuart Brand with fostering the idea that seeing Earth from space would change human consciousness, emphasizing the planet's uniqueness and fragility as a "tiny little planet, teeming with life, swimming around in a dead universe."
  • Eno recommends three books: 'Printing and the Mind of Man' for intellectual history, Christopher Alexander's 'A Pattern Language' for habitat design, and Norman Lewis's 'Naples 44' for its unique diary perspective on post-war Naples.
  • Eno recommends three albums: 'The Rural Folk Blues' for its raw Black American music, The Velvet Underground's third album which inspired his pop music career, and The Consolas' gospel record as an example of unmatched outsider music.
