We cannot answer these questions without taking a big step backward and look at our world history. At the time when the hunter-gatherers' lifestyle was still unchallenged. A long era dominated by peace as society didn't have any real hierarchy. Despite the division of labor, there were Sages and women were respected. Many anthropologists agree, prior to 3,000BC, wars didn't exist.

What a large load of crap. Just insane lies.

Hmm, psychopaths do lie constantly without remorse. I think we may have stumbled on something. Might you be a psychopath, earthcustodians?
