Recorded history
More complete writing systems were preceded by proto-writing. Early examples are the Jiahu symbols (c. 6600 BCE), Vinča signs (c. 5300 BCE), early Indus script (c. 3500 BCE) and Nsibidi script (c. before 500 CE). There is disagreement concerning exactly when prehistory becomes history, and when proto-writing became "true writing" However, invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age in the late Neolithic of the late 4th millennium BCE. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400–3200 BCE with earliest coherent texts from about 2600 BCE.
Prehistoric sites in Serbia
The Neolithic Starčevo and Vinča cultures existed in or near Belgrade and dominated the Balkans (as well as parts of Central Europe and Asia Minor) about 8,500 years ago. Some scholars believe that the prehistoric Vinča signs represent one of the earliest known forms of Writing systems (dating to 6000–4000 BC).
