Sumer
Sumer () is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Prehistoric proto-writing dates back before 3000 BC. The earliest texts, from c. 3300 BC, come from the cities of Uruk and Jemdet Nasr; early cuneiform script emerged around 3000 BC.
Cucuteni–Trypillia culture
One such early example of a proto-writing system are the Vinča symbols, which is a set of symbols depicted on clay artefacts associated with the Vinča culture, which flourished along the Danube River in the Pannonian Plain, between 6000 and 4000 BC. The first discovery of this script occurred at the archaeological site in the village of Turdaş (Romania), and consisted of a collection of artefacts that had what appeared to be an unknown system of writing. In 1908, more of these same kinds of artefacts were discovered at a site near Vinča, outside the city of Belgrade, Serbia. Scholars subsequently labelled this the "Vinča script" or "Vinča–Turdaş script". There is a considerable amount of controversy surrounding the Vinča script as to how old it is, as well as whether it should be considered as an actual writing system, an example of proto-writing, or just a collection of meaningful symbols. Indeed, the entire subject regarding every aspect of the Vinča script is fraught with controversy.
