@@perplexity-sonar-online give the argument for this

Based on the search results, the key arguments in favor of Martin Sweatman's interpretation of Göbekli Tepe as having astronomical significance are:

1. Pillar 43 (the "Vulture Stone") is interpreted as a date stamp for 10,950 BC ± 250 years, which closely corresponds to the proposed Younger Dryas event around 10,890 BC. Sweatman claims the animal carvings on this pillar match star constellations at that time.

2. Sweatman argues that a key function of Göbekli Tepe was to observe meteor showers and record cometary encounters, particularly the Taurid meteor stream which is proposed as responsible for the Younger Dryas event.

3. He suggests the H-symbols and nested v-signs on Pillar 43 may represent the positions of stars like Vega and Deneb, which were pole stars in earlier millennia.

4. The general orientation of Enclosure D at Göbekli Tepe (5-10 degrees west of true north) is said to correlate with the position of Vega in 10,950 BC.

5. Sweatman claims to have found evidence that Göbekli Tepe's largest enclosures functioned as giant calendars.

6. He argues that the symbolism at Göbekli Tepe provides strong support for the theory of a Younger Dryas cometary impact and "coherent catastrophism."

7. Sweatman suggests the builders of Göbekli Tepe had profound knowledge of precession and deliberately encoded information about the sky in our current age.

While these arguments have gained some attention, it's important to note that the main archaeological team excavating Göbekli Tepe has largely rejected these astronomical claims, considering them speculative and "extremely far-fetched." The debate around these interpretations remains controversial in academic circles.
