Look for Turdas archaeological site. 
 Turdas is a village near Deva, on the Mures river, in Transilvania, Romania. Eponymus site of the Vinca culture, represented by the exceptional figurines and pottery, painted with geometrical signs. A lot of Neolithic "books" made of little clay wheels are waiting to be discovered by the archaeologists... We were there, we found files from these books. Chronology: 5800-5200 BC.

And now let's read the message painted on this figurine from Turdas. On the neck, a down orientated V-sign. It's the Sky's action, all people from Old Europe knew that. On the belly two up orientated V-signs. Hmm... It's the Earth's action against the sky's action. On the hands, other two V-signs are orientated to human beings. Left and Right, Sky and Earth, four forces which are fighting for human birth, being and death... Who are the champions?

Here is a AA writing

Another Turdas figurine confirms our idea about
Angle Alphabet (AA) of Old European people.

Super Sensational:
near Turdas, at Tartaria, the archaeologists found an unknown writing
Just 5200 years BC!
Just  2000 years before "first" sumerian writing!
