Seven Lines of Evidence Supporting Constrained Discovery Over Diffusion

Gobekli Tepe: 9500 BCE
Carnac: 4800 BCE
Malta: 3600 BCE
Giza: 2600 BCE
Angkor: 800 CE
If diffused from one source, expect simultaneous
appearance. Instead: 7,000+ year spread.
SUPPORTS: Independent discovery at different times.

Each site uses locally optimal piezo materials:
Turkey/Egypt/Malta: limestone (local)
Stonehenge: dolerite from 260km (acoustic select)
Carnac: granite (local)
Maya: limestone (local)
Angkor: sandstone/laterite (local)
A diffused technology would use the SAME material.
SUPPORTS: Local optimization, not imported recipe.

True pyramids (Giza)
Stepped pyramids (Maya, Caral)
Temple mountains (Angkor)
Underground chambers (Malta Hypogeum)
Stone circles (Stonehenge)
Aligned rows (Carnac)
Passage tombs (Newgrange)
ALL different shapes. ALL same function.
SUPPORTS: Same physics, different cultural expression.

PNAS 2019: Bayesian analysis of 2,410 radiocarbon
dates from European megaliths confirms maritime
diffusion from NW France along Atlantic coast
(~4500 BCE). DNA confirms: Anatolian farmers
(from Gobekli Tepe region) migrated into Europe.
The BASIC principle was discovered locally.
REFINEMENTS then spread through contact networks.

If a lost civilization spread the tech globally,
their DNA would appear on every continent.
Ancient DNA studies (Nature 2020, PNAS 2016,
Nature 2023) show NO unknown ancestral population
appearing simultaneously across sites.
Megalith builders = local farmers + some admixture.
SUPPORTS: Local discovery, not imported knowledge.

Aboriginal Australian songlines: 65,000 years
of orally transmitted knowledge (navigation,
astronomy, ecology, law) WITHOUT WRITING.
This PROVES knowledge CAN persist for millennia.
So even if limited contact occurred,
oral transmission of "build stone, add water,
chant inside" could persist indefinitely.
SUPPORTS: Either model (diffusion OR discovery).

Nature 2020: DNA confirms Polynesian-Native
American contact ~1200 CE (Colombia coast).
Sweet potato: pre-Columbian transfer to Polynesia.
Contact DID occur — but LATE, long after
pyramids were already built on both continents.
SUPPORTS: Contact refined, not originated, tech.
