Look for Starcevo archaeological site. 
 Starcevo is a little village near Belgrade, Yugoslavia. Eponymus site of the Neolithic Central Balkan and Carpatho-Danubian civilization (Starcevo-Cris culture). First European pottery and the first painted with geometrical motifs pottery. Clay figurines of bird goddesses. A great ancient civilization on the Danube river, c. 6000 BC.

These clay figurines dressed in a rhombus "net" are sending to us the knowledge of the people who lived on the Danube river, 6000 BC. It's very important the V- sign from the bottom and top of the figurine. The angle of the bottom V-sign is up orientated; the angle of the top V-sign is down orientated, which indicates an active connection between Earth and Sky. The ancient science of the Sumerians, Egyptians and Greeks is older than the Sumerians, Egyptians and Greeks themselves. The homeland of this science is Old Europe. It was transmitted through the wonderful language of the Geometrical Sign. 8000 years of spirituality are coming to us from Starcevo...
