What would be the level of advancement required to have built Gobekli Tepe?

Gobekli Tepe fits well in creationist assumptions—not far from where we think Noah’s Ark probably landed, there’s an incredibly ancient monument that shows amazing human artistic skill and engineering ability, and it depicts lots of animals that aren’t in the area today.

Another piece of evidence that we uncovered—the once-fertile plain to the south of Göbekli Tepe is the site of the biblical Haran, a mere 25 miles away. This is where Abraham lived for several years during his family’s migration from Ur of the Chaldeans to the land of Canaan. It is where Terah settled and died, and from whence Isaac and Jacob both obtained their wives.

The first go-round demanded no more than dry-laid rock walls. The second building spurt involved pottery-making techniques.

piece of cake! I read that the statues at easter island were produced with water swelled wood to lift them slightly above ground, so a clever human could move giant objects and make wood rollers.
