I think you might appreciate the book The Dawn of Everything by David Graeber and David Wengrow [1]. They dive into the archaeological record and argue precisely that: that the common story of how civilization developed is very wrong, and that complex societies existed before the rise of agriculture, longer than is usually assumed. These findings at Göbekli Tepe appear very much in line with their theory.
