The claim
In 2017, Martin Sweatman and Dimitrios Tsikritsis argued that Göbekli Tepe's enclosures were observatories and that Pillar 43 records a 'Younger Dryas comet impact' — reading the carved animals as constellations and a date. The idea spread quickly online.
The excavators' reply
The Göbekli Tepe team responded directly on the DAI's Tepe Telegrams. Their objections, in plain terms: the animals are a consistent symbolic vocabulary repeated across many pillars, not a one-off star map; the enclosures were used and rebuilt across centuries, not a single dated event; and the pillar was carved well after the supposed impact. The site's imagery points to death and the body, not the sky.
Why we flag this
The comet reading is a genuinely published claim, and it's exciting — which is exactly why it's worth knowing that the people who dig the site do not accept it. We treat it the same way: an interesting idea, clearly labelled as contested, not the conclusion of the evidence.
