The Neolithic Revolution

Human society underwent what has been dubbed the neolithic revolution. This is when the ancient aliens came down from the heavens and taught us how to be farmers. The forces of production developed from hunting and gathering to settled agriculture and animal bandry. These societies could produce so much food that some people didn't have to devote themselves to productive labor. A non laboring minority becomes the ruling class who, initially, through sheer physical intimidation, are able to command and control the surplus production.
