As human societies became more and more cooperative, the ideas of trade, laws, and history became too overwhelming for one to remember. Writing and recording of information became a consistent practice as societies evolved.
The Tartaria Tablets are believed to be the oldest known surviving pieces of recorded documentation. The symbols on the tablets are believed to be Danube Script, found in Central European countries such as Romania. The nature of the Tartaria tablets are largely unknown, and are widely the principle of debate. It is believed the writings served for a burial purpose.
Other forms of ancient writing originate from Mesopotamia, in which Mesopotamians began using clay tokens to keep track of traded agriculture and other goods. This may also serve as an early example of currency, or money.
