Asia
The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley and the Yellow River shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states and empires developed in these lowlands.
Byblos
The site first appears to have been settled during the Pre-Pottery Neolithic B period, approximately 8800 to 7000 BC. Neolithic remains of some buildings can be observed at the site. According to the writer Philo of Byblos (quoting Sanchuniathon, and quoted in Eusebius), Byblos had the reputation of being the oldest city in the world, founded by Cronus. During the 3rd millennium BC, the first signs of a town can be observed, with the remains of well-built houses of uniform size. This was the period when the Canaanite civilization began to develop.
