Who made money?
Money has evolved essentially independently in every society. It all depends on what a culture views as valuable. In most Western nations, gold, silver and other precious metals are/were used as money. In other societies, beads or shells were used as money. Forms of money have been used in prisons where it might be cigarettes or drugs rather than federal reserve notes.
It is impossible to say who was the creator of money because money has in some form or another existed among every single society on Earth and even the oldest texts we have refer to it.
