Morality is an old concept but one that came about from the early days of civilisation. In small coummunities before towns and cities, most people would have known each other. There would have been very little need to explain to someone that stealing or murder was wrong as small communities would have been closely knit and therefore for these early people, their faith was focused on the outside world, animal spirits and ancestors who had shown them have to navigate the world.
It was with the advent of larger societies that the struggle for resources began and there needed to be some social convention to state what was acceptable and what wasn't. Moses had to come down from the mountain with commandments, but to most of us nowadays, those rules seem so obvious.
As with anything, we have slowly grown this body of morals and rules, far beyond their initial purpose which was to allow social cohesion in larger communities. For many it has now turned into a tool for control and those in control very rarely like to give it up.
