We should analyse the rationale, effect and influence on future civilisations of the introduction of metallic money by the Phoenicians in 1500 B.C.
Instead of trading in livestock, which were often cumbersome and difficult to transport, the Phoenicians invented metallic curved coins or tokens of value, thus avoiding the need for large cargo carrying ships when trading for goods.
Of course this was a highly advanced adaptation of the trading system of the time, an advance which you could well take on board even today.
I have seen you trying to catch pigeons to exchange for burgers at Burger King and I was hoping that some of the advances made by the Phoenicians more than 3000 years ago may appeal to you, if presented by an academic of suffiently high prowess, such as Professor F J Lewis, the very man with whom you are now fortunate to communicate!
