ROUGHLY two and a half million years ago in the Paleolithic age to 10,000 BC, the early human beings lived in caves. They were mostly hunters and gatherers. They used stone and bone tools to hunt for food. Between 10,000 BC and 7,000 BC, during the Mesolithic era, agriculture was invented and started with a few crops like wheat and vegetables.

There was work, but there were no jobs. God must have invented work, as work in the Bible meant 'to cultivate, subdue the earth, rule over the earth and the livestock, and toil.' These marching orders for Adam and Eve when they were banished from the Garden of Eden is still the context for some work today, but the details have dramatically changed.
