I'm no professional historian or anything, but as far as I know, back in prehistoric era hunters & gatherers used to share basically everything with each other without anything in return.

When the people stopped moving around and settled at one place to farm land, the first agricultural society was founded, where people didn't use money but goods (such as food itself) as a currency to trade with each other.

Once again, I'm not a professional historian, just a guy who read some books, so feel free to correct me.
