<human>:  How did the use of gold as money come about?
<bot>: Gold was first used as money in the Ancient Egyptian civilization, about 4,000 years ago. Egyptians were the first to use gold as money because it was easily transportable and had a high value. The first gold coins were minted in Lydia, a region in what is now Turkey, around 600 BC. The first coins in Greece were minted around 600 BC as well.
