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.
Borino
The Rhodopes are considered one of the cradles of European civilization. It is estimated that primitive people settled the region around 65,000 to 60,000 BC. The oldest evidence of human presence in the Rhodopes, flint instruments, was discovered in Borino by an archeological excavation near the current Orpheus Chalet. During fall and winter, eneolithic people lived in the caves of the region. Experts have discovered hearths from this time period dating from 4000 to 3000 BC in Yagodina Cave and idyllic figures connected with the cult to the Woman-Mother and the Sun Cult in Haramiska Cave near the Devil's Throat Cave.
