The earliest confirmed site of human activity on Cyprus is Aetokremnos, situated on the south coast, indicating that hunter-gatherers were active on the island from around 10,000 BC, with settled village communities dating from 8200 BC. The arrival of the first humans correlates with the extinction of the dwarf hippos and dwarf elephants. Water wells discovered by archaeologists in western Cyprus are believed to be among the oldest in the world, dated at 9,000 to 10,500 years old.
