The ancient findings that have come to light over the centuries, testify to the settlement of Greece dating back to the Paleolithic Age, which spanned from 11,000 to 3,000 B.C. The inhabitants at that time displayed nomadic characteristics. At many locations around present-day Greece, evidence of Neolithic dwellings have been discovered, from which we can draw conclusions such as what their living quarters were made of and what tools they primarily used (stone and clay). Again, signs of civilization and aspects of culture were already prevalent in Greece from the time of the Stone Age; while hub development took place later in the Bronze Age (from 3,000 B.C.), when more advanced cultures developed in the Greek lands.
