Money was according to history made by rulers to make them powerful and maybe even not to share resources with the soldiers who work for the ruler. And at that period or era, humans and other things were evolving. Same with money, as these evolutions took place the appearances were changing and from gold and silver coins (which were used first) made their way to coins made of metals and other metallic kinds of substances. Then emerged the printing of notes (AKA currency(officially known one)). And some people even today think money is everything. And that's how nothing evolved to everything. This was logical but I honestly think trades are better than currencies.(I learned in history so don't blame me for making it this big.
