Yeah it is speculation. Still it is interesting that a lot of religions talk about similar thing, great floods, fire raining from the sky etc. Even Atlantis.
This was found because it was buried, perhaps to build a new one on top. Lets say a massive event took place and destroyed everything, the only things that would survive would be the stuff underground...maybe. So its not completely ludicrous to think not much survived. If we had a massive disaster most of our fingerprint on the world would be lost, we don't build in stone anymore, im talking like 12,000 to 15,000 years.
Gobekli is apparently purposely buried, it has been shown not to be an area were people lived but rather a meeting spot or temple to the gods. The hand placement of the carvings is almost identical to that of the easter Island heads. Even if it was just made by a hunter gatherer civ it still throws our history out of whack because up until now we didn't think that was possible and we also thought "first comes the city then the temple", this would suggest otherwise. It means our timeline is out of whack, these stones needed like 500 men to just move them. Surely they had the wheel, huge organisation, the craftsmen for the carvings. Its just pretty mindblowing, this thing is like 7000 years older than the pyramids.
