The excavating institute's project page: site rediscovered in 1994, excavated since 1995; Pre-Pottery Neolithic A and B, about 9,500/9,250 to 8000/7,750 calBC; T-shaped pillars up to 5.5 m; now read as a settlement site with a pronounced ritual component.

Peer-reviewed formal analysis of the enclosures' floor plans: an underlying geometric pattern suggests three of the large stone enclosures were planned and initially built as a single project.

University release on the Haklay & Gopher study: the complex was built by Neolithic communities 11,500 to 11,000 years ago, and its planning was, in Haklay's words, a knowledge-based, top-down process carried out by specialists.
University release on a study in Time and Mind: V-shaped marks on a pillar may form a solar calendar and may record a swarm of comet fragments hitting Earth around 10,850 BC. Hedged throughout ('may', 'could').
Our own reading of the file, written from the sources on the other sheets. Opinion is marked as such.
The date is the solid part. The DAI places the site in the Pre-Pottery Neolithic A and B, from about 9500/9250 to 8000/7750 BC. That is before pottery, which is why the site matters: very early Neolithic communities organised the quarrying, carving and raising of pillars up to 5.5 metres high. A 2020 study goes further and argues that three of the large enclosures were laid out together on a geometric plan.
Interpretation has moved. For its first twenty years Göbekli Tepe was read as a primarily ritual site, even a mountain sanctuary. Newer finds of domestic activity have led the DAI to describe it as a settlement with a pronounced ritual component. That shift is ordinary science: more digging, better answers.
The comet reading is where the argument becomes heated. Sweatman and Tsikritsis matched animal carvings to star patterns and read a date of 10950 BC. The excavators replied that this date is 700–1000 years older than the oldest radiocarbon date for that enclosure, and that the site's dates mark the end of the Younger Dryas rather than its beginning. We label the dating claim confirmed. The astronomical reading remains a proposal that the excavators reject.
Martin Sweatman and Dimitrios Tsikritsis, of the University of Edinburgh, argue in a peer-reviewed journal that the animal carvings on Pillar 43 are star asterisms and form a date stamp for 10950 BC ± 250 years, close to the proposed Younger Dryas comet event. On their reading the site was used to observe meteor showers and record cometary encounters, and may be the smoking gun for a Younger Dryas impact. A 2024 Edinburgh study extended the idea, reading V-shaped marks on a pillar as a solar calendar.

Peer-reviewed proposal that pillar carvings match star asterisms and that the 'Vulture Stone' is a date stamp for 10950 BC ± 250 years, close to the proposed Younger Dryas event; the authors ask whether the site is the 'smoking gun' for a cometary encounter.

The excavators' plain-language version of their reply: more than 60 T-pillars are known, the selection of a few is arbitrary, and the proposed date is 700–1000 years older than the oldest radiocarbon date for Enclosure D.

Position statement: a century of fieldwork has produced no evidence for an advanced global Ice Age civilisation, and the idea of one destroyed by comets has been debated and refuted for at least 140 years.
