How so? The suggestion is that Gobekli Tepe is the original T-shaped pillar school of agricultural knowledge, thousands and thousands of years old, and which was subsequently replicated in another region of the world where agricultural knowledge also rapidly expanded through human industry.
That’s pretty clear. That it has not been academically demonstrated is of course relevant - but then, the research at Gobekli Tepe came to a screeching halt around the same time this idea was first proposed, so perhaps it is important to do more than just scratch the surface of the subject ..
Maybe you'd be happier if one used the more neutral term "complex society" instead of "civilization", since the latter has baggage. I imagine we can agree that some societies are more complex than others but that societal complexity is orthogonal to inherent cultural value.
Also, it is spelled Göbekli Tepe.
