Inquiry Threads

This document holds working hypotheses, speculative frameworks, and connective ideas that are not yet ready for the Dispute Ledger. A thread is not a claim we can falsify today. It is a structure we suspect might be true, worth tracking as evidence accumulates, and potentially able to explain multiple ledger claims if it holds.

Threads and claims inform each other. A falsification in the ledger can strengthen a thread, and a thread can suggest new claims to pursue. Together they form a connected picture.

Confidence scale

Level	Meaning
Speculative	Interesting idea with logical appeal but no direct supporting evidence identified yet. Worth tracking.
Plausible	The logical chain holds. Mechanisms check out against what is already known. No direct falsification.
Likely	Supported by some independent evidence. Weakening competing explanations.
Strong	Well-supported by cross-cutting evidence from multiple lines (ledger claims, independent data, multiple sites).

Thread 1: Ice Age civilization reset

Hypothesis: It is not settled whether complex human cultures, potentially reaching civilizational peaks that required technical sophistication but fell well below spacefaring capability, could have emerged during prior interglacial windows. The Eemian interglacial (~130-115 kya) provided 15,000 years of warm, stable climate with cognitively modern Homo sapiens present and capable. The mainstream position that nothing of significance occurred is an absence of evidence treated as evidence of absence, not a proven conclusion. Dismissing the possibility requires an explanation for why 15,000 Eemian years produced so little when 7,000 Holocene years produced the Great Pyramid.

Confidence: The windows are established fact. Whether they produced complex cultures is an open question the mainstream has not addressed with affirmative evidence, only with the assumption that absence proves absence.

Status: Active

The Chain:

1. The geological reality of glacial-interglacial cycles is not in dispute. Ice sheets kilometers thick have repeatedly advanced across northern landmasses and retreated. The pattern runs roughly every ~100,000 years, with interglacial windows of ~10,000-15,000 years. The current Holocene interglacial is ~11,700 years in, near the typical end of the comfortable window.

2. Humans survived through these cycles. Our existence today proves continuous human presence through at least the last glacial maximum (~20,000 years ago) and plausibly much deeper into the past. We were not wiped out.

3. Homo sapiens has lived through only three full interglacials, but the hominin lineage extends far deeper. Our species emerged ~300,000 years ago. In that span, we have completed only two prior interglacials (and are now in a third). But the cognitive architecture that produced us, symbolic thought, tool-making, fire, language, was building across a much longer ramp:

   Interglacial	MIS Stage	Dates	Duration	Hominin present
   MIS 15	~621-563 kya	~58,000 years	Homo heidelbergensis, common ancestor of sapiens and Neanderthals
   MIS 13	~524-478 kya	~46,000 years	Homo heidelbergensis
   Hoxnian	MIS 11	~424-374 kya	~50,000 years	Homo heidelbergensis, longest interglacial of the last half-million years; sea levels 20m higher than today
   Purfleet	MIS 9	~337-300 kya	~37,000 years	Homo heidelbergensis through the earliest sapiens at the end
   Aveley	MIS 7e	~242-230 kya	~12,000 years	Sapiens + Neanderthals; sapiens populations small and fragmented; possibly pre-symbolic
   Eemian	MIS 5e	~130-115 kya	~15,000 years	Sapiens fully present and cognitively capable; Neanderthals in Europe
   Holocene	MIS 1	~11.7 kya-present	~11,700 years (ongoing)	Sapiens, this is us

   Three interglacials for sapiens specifically, but six for the lineage that built our cognitive architecture. Homo heidelbergensis controlled fire, built shelters, and carried a brain of ~1,200 cc through interglacials lasting 50,000+ years. The capacity for symbolic thought does not appear at a single speciation event, it ramps across the gradient. And with it, the awareness of the cycles themselves: ice advancing, ice retreating, the world flooding, the world warming, over and over, across half a million years of hominin experience.

   The Eemian is the critical sapiens case, and it was more favorable than the Holocene. It was ~2°C warmer, with sea levels 6-9m higher, CO₂ at ~280 ppm, and productive ecosystems across Africa, Europe, and Asia. It lasted 15,000 years, more than double the ~7,000 years the Holocene needed to progress from hunter-gatherers to pyramid-capable civilization. And by the Eemian's midpoint, Homo sapiens possessed the full cognitive suite for complex culture: shell beads, engraved ochre, pyrotechnology, marine foraging, and long-distance trade networks.

   Yet the Eemian produced no agriculture, no settlement, no monumental architecture. If the same species with the same brain had 15,000 warm years and produced no civilization, what was the limiting factor?

   The demographic threshold model (Powell et al. 2009) is the strongest candidate answer: cultural complexity requires population density. Small, fragmented Paleolithic populations could not sustain innovations across generations, skills were invented and lost. The Holocene started from an unusually favorable baseline: sapiens was already globally distributed by 12,000 years ago, with dense populations on multiple continents, enabling parallel development and the cumulative cross-pollination that drives complexity. The Eemian started from thin, Africa-confined populations. Same brain, same species, but an order of magnitude fewer brains in contact with each other.

   The sedimentary record problem: Eemian deposits are well-preserved and extensively studied across three continents, lake sediments, peat bogs, cave deposits, fossil reefs. They show a detailed record of hunter-gatherer activity with zero civilizational signature. If an Eemian civilization existed, it would have to have been extraordinarily small, extraordinarily clean, or entirely coastal (now 6-9m underwater), any of which limits the kind of megalithic stonework the hypothesis centers on.

   The cultural gradient, the ramp, not the jump: The 300,000-year sapiens boundary is a fossil-dating convenience, not a cognitive boundary. Neanderthals, who diverged from our lineage ~500,000 years ago, produced cave art, wore eagle-talon jewelry, buried their dead with grave goods, and possessed speech-ready hyoid bones. Their common ancestor with us, Homo heidelbergensis (~700-200 kya), controlled fire, built shelters, and had a brain of ~1,200 cc. The gradient from erectus through heidelbergensis through early sapiens is a smooth ramp in cognitive architecture across a million years, not a sharp jump at 300,000.

   This matters because it extends the window of potential cultural awareness of glacial cycles. Hominins have been experiencing the ice come and go for at least half a million years. Oral traditions can persist across extraordinary timescales: Aboriginal Australian oral histories are documented to have survived over 10,000 years, referencing sea-level rises and landscape changes that match geological records. A hominin lineage that experienced multiple interglacials, each with rising seas, flooding, rebounding ecosystems, and the return of warmth, would carry that expectation forward. The cycles would become an anchor for culture, religion, and origin narrative: the flood that ends the world, the warmth that returns it, the ancestors who built before.

   The implications are not merely that "they had time." It is that the Holocene did not start from cultural zero. It started with a species that had seen the ice retreat before. The moment the Younger Dryas ended and the Holocene stabilized, populations that had survived the preceding glacial period with a cultural memory of what happens next would recognize the window opening. Göbekli Tepe, monumental stone architecture built by hunter-gatherers within a few centuries of the Holocene's stabilization, may be evidence not of sudden innovation but of expected resumption: the builders knew what was coming and were ready.

4. What surviving evidence would look like is addressed separately in Thread #2 (What Survives Geological Time), the full durability analysis: orbital stability, nuclear signatures, stone preservation, and the detection problem.

5. The key prediction: If the Eemian window was open and the burden is on the mainstream to prove nothing happened (rather than on challengers to prove something did), then megalithic structures that appear to predate their attributed builders are not anomalies to be explained away, they are testable predictions of a framework the mainstream has never established affirmative evidence against.

Key constraint: No positive claim is made that any prior interglacial complex culture or civilization existed. The hypothesis only establishes that the Eemian window was long enough, warm enough, and inhabited by cognitively modern humans, and that the mainstream dismissal of the possibility does not rest on any affirmative evidence that nothing occurred. It is an absence of evidence treated as settled proof, which is a methodological error, not a finding.

What would strengthen:

• Dating evidence at any megalithic site that places construction before the attributed culture
• Direct accounts from a site-attributed culture stating they inherited the site or did not build it
• Independent evidence of pre-attribution human presence at any megalithic site
• Any megalithic structure found under glacial or post-glacial deposits predating the Holocene

What would weaken:

• Conclusive dating that ties a major megalithic site firmly to its attributed culture's active period
• Absence of pre-attribution human activity layers at multiple megalithic sites
• Any evidence that megalithic construction is impossible without an existing complex civilization at the site

Thread 2: What survives geological time

Hypothesis: A complex human culture that reached a civilizational peak during a prior interglacial would leave an extremely limited set of detectable artifacts after 100,000+ years of glacial grinding, erosion, and chemical weathering. Understanding the full spectrum of what could and could not survive is essential for any claim about pre-Holocene cultural complexity, whether affirming or denying one.

Confidence: Likely, the physical mechanisms are well-understood. The uncertainty is in detection limits, not in the degradation processes themselves.

Status: Active

What Would NOT Survive:

• Organic materials (wood, textiles, paper), decay within centuries under most conditions
• Base metals (iron, steel, copper), oxidize and erode, especially under ice sheet pressure and chemical weathering; structural remnants would be unrecognizable after 10,000+ years
• Concrete and fired brick, crumble under freeze-thaw cycling, ice loading, and vegetation encroachment; reinforced concrete fails as rebar corrodes and spalls
• Electronics, plastics, composites, degrade through UV, temperature cycling, and chemical breakdown; plastics fragment into microplastics but lose all original structure
• Low-Earth-orbit satellites, atmospheric drag decays LEO orbits within years to decades; no debris remains

The Spectrum of Orbital Stability:

Not all orbital debris decays equally:

• LEO (below ~2,000km): orbital decay in years to decades due to atmospheric drag. Clears quickly without active station-keeping.
• MEO (~20,000km, GPS orbits): stable on timescales of thousands to millions of years depending on altitude and eccentricity.
• GEO (~36,000km): very long-term stable, tens of millions of years; subject to long-term perturbations from lunar/solar gravity and Earth's non-spherical gravitational field.
• High elliptical and highly eccentric orbits: stability varies wildly by specific orbit.
• LAGEOS-1 (NASA, 1976), a passive aluminum sphere with retroreflectors at ~5,800km, has a calculated orbital lifetime of ~8.4 million years. Its plaque was designed by Carl Sagan to communicate across deep time.

Mechanisms That Could Destroy Even High-Orbit Artifacts:

Over geological timescales, no orbit is truly stable:

• Gravitational perturbations from the Moon, Sun, and other planets slowly alter orbital parameters. Over millions of years, these perturbations can lower perigee enough for atmospheric capture.
• Solar radiation pressure and solar storms gradually modify orbits, low-density objects (balloons, lightweight satellites) are most affected. Dense objects like LAGEOS are minimally affected, but repeated major CME events over millions of years contribute cumulatively to orbital perturbation. Solar-driven atmospheric expansion also increases LEO drag, but this is irrelevant at GEO/MEO altitudes where the atmosphere is effectively absent.
• Micrometeoroid impacts are random but cumulative. Over millions of years, statistically probable impacts could alter momentum, fragment the object, or degrade reflective surfaces.
• Passing bodies, rogue planets, large asteroids, or close stellar passages (extremely rare), can perturb the entire solar system's orbital dynamics. The probability within a few million years is negligible.
• Earth's magnetic pole reversals and axial tilt do not directly affect orbital mechanics, orbital dynamics respond to mass distribution and gravitational field, not magnetic field. Axial tilt precession (~26,000-year cycle) and larger Milankovitch variations (~41,000 and ~100,000-year cycles) change insolation patterns but not orbital stability for satellites.
• Large impacts on Earth could eject debris into orbital paths, potentially colliding with existing satellites. The probability over millions of years is non-trivial.

The Detection Problem:

Could an ancient satellite exist in stable orbit today and simply not be found? Possibly:

• Passive objects with low albedo (non-reflective surfaces) are difficult to detect with optical telescopes. The Space Surveillance Network tracks ~47,000 objects and catalogs ~34,000, predominantly tracked because their orbits are known or intersect active spacecraft. An unknown passive object in a stable orbit outside heavily monitored zones (LEO) could plausibly go undetected.
• A reflective object (like LAGEOS) would be more visible but still small (~60cm). If its orbital parameters were sufficiently different from known satellite populations, it might not be correlated and could remain as an unassociated detection in survey data.
• Objects in MEO and GEO are less thoroughly monitored than LEO. The tracking gap is larger.
• Unexplained radar and optical detections do exist in space surveillance data, classified as "uncorrelated tracks", but these are typically attributed to debris or sensor noise.

Nuclear Weapon Signatures:

A common claim is that past nuclear detonations would be detectable in geological strata. The reality is messier.

Half-life constraints by isotope:

• Iodine-129, 15.7 million years. Survives across multiple glacial cycles. Baseline exists from natural fission; an anomalous spike could persist in undisturbed strata.
• Plutonium-239, 24,100 years. After 120,000 years, ~97% has decayed. Faint but potentially measurable in ideal preservation environments.
• Cesium-137 (~30 years), Strontium-90 (~29 years), Iodine-131 (~8 days), erased before the next human generation.
• Carbon-14 (~5,730 years), fades below detection after ~50,000 years.

Anomalous isotope ratios: The Oklo natural reactor (Gabon, ~1.7 billion years ago) proves that fossil fission events are detectable across deep time, not because radiation lingers, but because the stable end-products are permanently locked into the mineral matrix at statistically anomalous ratios.

The preservation problem: Ice cores going back ~800,000 years trap atmospheric signals, but glacial advance physically scours and reworks the surface. A nuclear plume dispersed across the atmosphere gets mixed into ice, sediment, and ocean, then churned by kilometers of moving ice over thousands of years. Finding an anomalous iodine-129 spike from 200,000 years ago requires a lucky sedimentary basin, deep, anoxic, untouched by glaciation, and someone specifically looking for it.

Conclusion: Technically possible. Not practically falsifiable in either direction. The conditions needed (long-lived isotope, concentrated in an undisturbed basin, shielded from glaciation, found and correctly interpreted) stack enough low-probability events that neither presence nor absence of a signal can be used to reliably conclude anything. The glacial blender is too thorough. (This analysis is also recorded as Spent Objection #1 in the Dispute Ledger.)

Non-Orbital Artifacts That Could Survive:

• Dense, massive granite and basalt, capable of surviving ice sheet loading, chemical weathering, and freeze-thaw cycles for hundreds of thousands of years. Shape and surface finish degrade slowly but recognizably.
• Structures buried under sediment or glacial till could be preserved far longer, depending on the depositional environment.
• Objects carved from extremely hard stone (diorite, quartzite) or crystalline materials (diamond, sapphire) could survive indefinitely on geological timescales with minimal degradation.
• Deep underground structures (mines, tunnels, chambers) would be the most survivable category, protected from surface erosion, ice movement, and climate cycling.

Molecular-Scale Remnants, Chemical and Isotopic Signals:

Beyond macroscopic artifacts, a pre-glacial civilization would leave molecular-scale traces in the sedimentary record. Whether these survive depends on the durability of the molecule and the preservation of the depositional layer.

Category	Could survive a glacial cycle?	Detectable as anthropogenic?
Heavy metals (lead, mercury, cadmium)	Yes. These are elements, they don't decay.	Potentially. An anomalous concentration in an undisturbed sediment layer could be anthropogenic. But glacial scouring dilutes them across enormous volumes of reworked regolith.
Industrial isotopic shifts (Suess effect: ¹³C/¹²C depletion from fossil fuel burning)	Yes. Isotope ratios are preserved in layered sediments.	Potentially. An anomalous carbon isotope shift in deep sediment from an unglaciated basin could theoretically be detected. Same mechanism as the nuclear isotope question.
Agricultural nitrogen (Haber-Bosch δ¹⁵N signature)	Yes. Preserved in sedimentary nitrogen.	Same constraints: requires undisturbed, stratified sediments in a basin untouched by glaciation.
PFAS / "forever chemicals"	Unclear. C-F bonds are the strongest in organic chemistry, and some PFAS could theoretically persist in anoxic sediments.	No useful data. PFAS have only existed since the 1940s, so empirical half-life on 100,000-year timescales is unknown. Extrapolation is speculation.
Plastics / microplastics	No. Organic polymers degrade from UV exposure, oxidation, freeze-thaw cycling, and glacial grinding. Polymer chains fragment into monomers over timescales far shorter than a glacial period.	No. The monomers (ethylene, propylene) are identical to natural organic compounds. Degraded plastic is indistinguishable from degraded biomass.
Engineered nanoparticles (carbon nanotubes, nanoscale metal oxides)	Unclear. Carbon nanotubes are structurally durable but would be physically fragmented by ice loading.	No. Once fragmented and dispersed, they are indistinguishable from naturally occurring carbon structures and mineral grains.
Cement chemistry	No. Portland cement degrades to calcite, identical to natural limestone.	No. The mineral end-product is geologically common. The processing signature is entirely lost.

The common failure mode is layer destruction, not molecular decay. A nuclear test plume, an industrial lead emission, or an agricultural nitrogen pulse enters the atmosphere, settles into topsoil and lake sediments, and forms a thin anthropogenic layer, a distinct horizon in the stratigraphic record. Then a kilometer of ice grinds across the continent, churns that layer with hundreds of meters of bedrock and regolith, and spreads the resulting slurry across thousands of square kilometers. The molecules persist. But they are diluted by nine orders of magnitude and distributed too thinly to form a readable signal, even if someone knew exactly where to core.

The only sedimentary environments that reliably escape glacial disruption are deep ocean floors, equatorial lake basins, and permanently anoxic depressions isolated from surface drainage. A faint signal could persist there. But targeting those environments requires knowing where the civilization was. With the surface evidence destroyed, the target is unknown, and there are millions of square kilometers of viable sediment to search.

Implications for the Ice Age Reset Hypothesis:

If a prior interglacial civilization reached orbital launch capability, some number of their satellites could plausibly remain in orbit today. A single LAGEOS-class object, solid, passive, high orbit, could survive millions of years. The "we'd see satellites" argument is weaker than the simple version assumes. The constraint is not "satellites don't last" but rather "the detectable signature of orbital technology over geological time is uncertain."

Conversely, the absence of detected orbital artifacts does not rule out non-orbital pre-glacial civilizations. And the sedimentary record from the Eemian is sufficiently well-preserved that a large, inland, agricultural civilization would likely have left detectable traces, imposing a scale constraint on any hypothesized pre-Holocene civilization.

Thread 3: The cargo-cult adoption pattern

Hypothesis: Later cultures encountering more sophisticated artifacts from prior societies adopt them as sacred, incorporate them into their own sites, and attempt to replicate them, producing visibly inferior copies. This dynamic is well-documented and accepted across archaeology for objects, sacred sites, and cultural artifacts. The Inca reoccupying Tiwanaku as a world-creation site is textbook. The Inca inheriting Sacsayhuamán's megalithic walls is not. The inconsistency is that the same phenomenon, a later culture finding more sophisticated construction than it can produce and treating it as sacred or inherited, is accepted for objects and sites but blocked for the architecture at those very sites. And critically, the prior builders need not have been hyper-advanced, merely capable of techniques the later culture had lost, the same way medieval builders lost Roman concrete.

Confidence: Likely. The regression examples themselves are textbook and non-controversial. The interpretive double standard is the hypothesis under examination.

Status: Active

Confidence: Likely. Cargo-cult adoption is well-documented in anthropology and archaeology. The pattern of later cultures treating earlier structures as sacred is uncontroversial. The dispute is about whether the same dynamic extends to the construction of the structures themselves.

Status: Active

Accepted Cargo-Cult Adoptions, Where the Dynamic Is Uncontroversial:

Site / Artifact	Earlier Culture	Later Culture	The Adoption	Status
Tiwanaku / Pumapunku	Unknown builders (pre-Tiwanaku?)	Tiwanaku (c. 500-1000 CE), then Inca	Inca treated Tiwanaku as the site of world-creation (Viracocha). They did not claim to have built it. They built inferior stonework around the existing megalithic core.	Accepted. The Inca reoccupying and revering Tiwanaku as a sacred site of prior gods is textbook.
Roman concrete	Roman engineers (1st-2nd century CE)	Medieval builders	The Pantheon's unreinforced concrete dome remained unmatched for 1,500 years. Roman marine concrete (hardens underwater) was only decoded in 2017. Medieval builders used simpler lime mortar.	Accepted. "Lost Roman concrete" is the framing. No one disputes that medieval builders couldn't replicate it.
Mycenean masonry	Mycenean Greeks (c. 1400-1200 BCE)	Iron Age / Homeric Greeks (c. 800-500 BCE)	The Lion Gate at Mycenae and the Cyclopean walls were attributed by classical Greeks to the Cyclopes, they literally believed giants built them because they couldn't conceive of human construction at that scale. Iron Age Greeks built megaron halls and mudbrick walls around the existing megalithic fortresses.	Accepted. The term "Cyclopean masonry" is the classical Greeks' own admission that they couldn't match the earlier work.
Göbekli Tepe	Pre-pottery Neolithic (c. 9600-8000 BCE)	Later Neolithic cultures	The site was deliberately buried, not destroyed, around 8000 BCE. Later cultures built smaller, cruder enclosures nearby. The earliest enclosure (Layer III) has the largest, most sophisticated T-pillars. Later enclosures (Layer II) are smaller and simpler.	Accepted. The regression from Layer III to Layer II is documented.
Egyptian stone vessels	Predynastic (pre-3000 BCE)	Dynastic Egyptian	Predynastic granite and diorite vessels show micron-scale rotational symmetry, measurable with modern metrology. Later dynastic vessels are visibly less precise. The pyramid-builders may have been working from inherited artifacts whose production techniques they no longer possessed.	Regression is observable. Mainstream attributes it to "changing funerary practices" rather than lost technique.

The Block, Where the Same Dynamic Is Rejected:

When the same pattern, a later culture encountered more sophisticated construction, treated it as sacred or inherited, and could not replicate it, is applied to megalithic architecture, the conclusion is blocked. The evidence is the same. The dynamic is the same. The interpretive boundary is maintained by convention.

Site	Evidence of Adoption	Mainstream Position	Blocked Conclusion
Sacsayhuamán	Inca told Spanish chroniclers the megalithic walls predated them. Two distinct masonry tiers, the lower cyclopean walls (128+ tons, no mortar, paper-thin joints) are structurally different from the upper courses. Killke pottery dates the site to 900 CE, predating Inca expansion.	The Inca built all of Sacsayhuamán in the 15th century (UNESCO, Bauer 2010).	The Inca inherited the megalithic core from a prior culture and built the upper courses around it, exactly as they did at Tiwanaku.
Baalbek	The Trilithon (800-1000 ton stones) sits beneath the Roman Temple of Jupiter. The podium wall construction is stylistically unrelated to Roman architecture. The "Stone of the Pregnant Woman" (1,650 tons) remains abandoned in the quarry, the Romans could not move it.	The Romans quarried, transported, and placed the Trilithon in the 1st century CE (German Archaeological Institute).	The Romans found an existing platform and built their temple on top of it, exactly as the Mycenean Greeks built on Cyclopean foundations later cultures couldn't reproduce.
Osireion at Abydos	Megalithic granite and sandstone construction without mortar, completely different from Seti I's adjacent New Kingdom temple. Sits at lower elevation. Strabo (1st century BCE) didn't know who built it. Frankfort's dating rests on one cartouche, consistent with New Kingdom restoration.	Built by Seti I in the 19th Dynasty (Frankfort 1933, Brand 2000).	Seti I restored and inscribed an existing structure built by an earlier culture, exactly as the Inca inscribed their temples onto Tiwanaku.
Giza Plateau	The Sphinx and Valley Temple show water erosion inconsistent with the arid conditions of 2500 BCE. The Great Pyramid contains internal construction features (granite sarcophagus, relieving chambers) that have no Old Kingdom parallel.	All Giza monuments are Fourth Dynasty, c. 2600-2500 BCE (Lehner, Hassan, Hawass).	The Old Kingdom found existing structures at Giza, restored and modified them, and built their pyramids adjacent.

The interpretive boundary is not about whether cultures adopt prior artifacts, that is uncontroversial. It is about what scale of artifact a culture is permitted to have adopted. Finding a granite vase and putting it in a temple is acceptable archaeology. Finding a granite temple and building a mudbrick pyramid next to it, then claiming you built both, that interpretation is blocked, because it would require the pre-existing construction to have been completed by a prior culture with capabilities the later culture lacked. And that capability gap is what the chronological framework cannot accommodate.

The capability gap need not be shocking. No lost civilization with rockets and satellites is required. The gap between Roman concrete and medieval lime mortar is modest, but it took 1,500 years to close. The gap between Old Kingdom granite precision and Middle Kingdom stonework is observable, and never closed. The prior builders needed only to possess techniques the later culture had not independently discovered: precise stone-cutting, large-block transport, water-integrated design. These are specific, modest capabilities that produce outsized results in stone.

What would strengthen:

• Architectural analysis documenting visible quality differences between megalithic cores and later additions at the same sites (already present at Sacsayhuamán, the Osireion, Baalbek)
• Cultures' own testimony that they inherited the construction rather than built it (Inca at Sacsayhuamán and Tiwanaku, classical Greeks at Mycenae)
• Metrological data showing precision regression from earlier to later artifacts across multiple civilizations

What would weaken:

• Discovery of construction records definitively attributing the most sophisticated megalithic layers to the cultures currently credited
• Demonstrating that the construction at the interface between megalithic core and later addition is continuous (single phase) rather than sequential
