Gobekli Tepe et are antediluvian, buried by the upper reaches of mega-tsunami. Not buried deliberately, nor by landslides (how can a hilltop be buried by a landslide?).

The YDIH is being promoted because it distracts from cyclic cataclysm.

10,000BC was the last one.

The next one is 2048.

The great year is 24,000 years. Cataclysm happens every 12,000 years.

So, causation is not due to impact (impact cannot be cyclic), and not due to solar outburst.
