Göbekli Tepe
Stone enclosures ringed by carved T-shaped pillars, built in south-eastern Turkey more than 11,000 years ago, and the claims of a lost civilisation and a comet strike.
The question Who built Göbekli Tepe’s megaliths 11,000+ years ago, and does it prove a lost advanced civilisation or a comet catastrophe?

Hunter-gatherers build stone enclosures ringed by carved T-shaped pillars
UNESCO’s listing says the structures were “erected by hunter-gatherers in the Pre-Pottery Neolithic age between 9,600 and 8,200 BCE”. Some pillars are up to 5.5 metres tall and carved with wild animals.

Enclosure D, home of the “Vulture Stone”, gives the site’s oldest dates
Organic matter in the wall plaster between Pillars 41 and 42 was dated to 9745–9314 cal BC, and three charcoal samples from near the floor to 9664–9311 cal BC (95.4% confidence).

The ranges in their 2016 blog (9745–9314 cal BC) imply about 1,200–1,650 years. Both are shown. - c. 8000 BCconfirmed
Building stops and the site is abandoned
Projectile points typical of the latest Pre-Pottery Neolithic are missing, and the excavators date the end to around 8000 BC. The whole mound, up to 15 metres high, is human-made deposit.

A survey by the universities of Istanbul and Chicago records the site, but not its buildings
Peter Benedict logged it as site V 52/1, “littered with flint artifacts”, and counted 2,996 pieces of flint. The survey project ran from 1963 to 1972; his report, published in 1980, is quoted, but the year of his visit is not given in what we read.

Excavations begin under Klaus Schmidt of the German Archaeological Institute
On a 1994 tour of Neolithic sites Schmidt noticed limestone blocks like the tops of T-shaped pillars. Digging began the next year with the Şanlıurfa Museum, and his team carried on after his death in 2014.

Enclosure D’s floor is reached, revealing two central pillars about 5.5 metres tall
The pillars carry carved arms, hands, belts and loincloths. Because no domesticated plants or animals are known from the site, the excavators concluded its builders “were still hunter-gatherers”.

Two Edinburgh engineers publish a paper reading Pillar 43 as a date stamp for a comet strike
Martin Sweatman and Dimitrios Tsikritsis matched carved animals to star patterns and argued that the “Vulture Stone” records 10,950 BC ± 250 years, close to a proposed comet impact at the start of the Younger Dryas cold period.
T1Sweatman & Tsikritsis, MAA, 2017abstract - 2017confirmed
The excavators publish a reply in the same journal
They wrote that the proposed date is older than Enclosure D’s oldest radiocarbon date, that many pillars are not in their original positions, and that the buildings may have been roofed, which would limit sky-watching.

UNESCO inscribes Göbekli Tepe on the World Heritage List
The World Heritage Committee inscribed it at its 42nd session in Manama, Bahrain, under criteria (i), (ii) and (iv). The listing calls the structures “monumental communal buildings (enclosures)”.

Soundings in 2015–2019 found round houses, hearths, a sub-floor burial of at least three people and an 8-metre rock-cut pit that may have been a rainwater cistern. The team now says people lived at the site, and that the fill of the big buildings slid in from higher slopes.

Pillar 43 records a comet strike in 10,950 BC
Is the “Vulture Stone” a date stamp for a comet impact around 10,950 BC?
- confirmed
The 2017 paper dates Pillar 43 to 10,950 BC ± 250 years by matching its animals to constellations
It used the Stellarium software set to Şanlıurfa and put the chance of an accidental match at less than one in 5 million. It read the small headless man as marking “probably the worst day ever in human history since the end of the ice age”.

Enclosure D’s oldest radiocarbon dates are later than the proposed date
The excavators: the date “is still 700-1000 years older than the oldest radiocarbon date so far available for Enclosure D”. The paper’s authors accept a gap of “around 1000 years or more” but suggest Pillar 43 was carved before its wall.

Whether the carvings are star maps at all
The excavators call the choice of pillars “incredibly arbitrary”; the authors reply that the critics did not test their statistics. A third comment, which offers a star-map reading of its own, found the paper’s matches “do not correlate well with the actual spatial pattern of stars”.

A comet impact started the Younger Dryas cold period
A 2023 review by 13 scientists concluded the Younger Dryas impact hypothesis “should be rejected”. The 2017 paper and its authors’ reply cite studies in its favour, including a platinum anomaly reported in 2017.

Key claim: Pillar 43 records a comet strike in 10,950 BC
Peer-reviewed papers stand on both sides. No record dates the carving of Pillar 43 itself: the dates come from wall plaster and nearby charcoal, and its authors concede the pillar’s date “is not known with much confidence”.

Bullshit meter
- No step is Unverified or Disproven.
- Key claim contradicted by tier 1? Partly. Tier-1 dates put Enclosure D’s oldest material roughly a thousand years after 10,950 BC, and a 2023 review rejects the impact. The authors answer that the pillar may be older than its wall, which no record settles.
