And it was a hierarchy of actualization (power to and power with) not power over as in a dominance hierarchy, which is what we live in. If you are not able to make the distinction between the two, you have no business trying to discuss this any further.

In fact, in Çatalhöyük, a settlement of about 10,000 from the Neolithic era, where extensive archeological artifacts have been discovered, giving great insight into the way the society functioned, it is clear that the inhabitants were both egalitarian, non-hierarchical, and largely peaceful.
Çatalhöyük has strong evidence of an egalitarian society, as no houses with distinctive features (belonging to royalty or religious hierarchy, for example) have been found so far. The most recent investigations also reveal little social distinction based on gender, with men and women receiving equivalent nutrition and seeming to have equal social status, as typically found in Paleolithic cultures. Çatalhöyük
The settlement seems to have been very orderly, efficient, and successful. The inhabitants gained skill in agriculture as well as the domestication of animals, and it is the first place in the world where mining and smelting of metal is in evidence. Pottery and the making of obsidian tools seem to have been major industries, although weapons of war and fortifications are notably absent. Çatalhöyük existed from approximately 7500 BC to 5700 BC and flourished around 7000 BC. It was a fully-functioning culture that appears to have done quite well without the coercive and controlling hierarchies of the patriarchy that was to come soon after.
