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.
Ostracon
In October 2008, Israeli archaeologist, Yosef Garfinkel of the Hebrew University of Jerusalem, has discovered what he says to be the earliest known Hebrew text. This text was written on an Ostracon shard; Garfinkel believes this shard dates to the time of King David from the Old Testament, about 3,000 years ago. Carbon dating of the Ostracon and analysis of the pottery have dated the inscription to be about 1,000 years older than the Dead Sea Scrolls. The inscription has yet to be deciphered, however, some words, such as king, slave and judge have been translated. 
The shard was found about 20 miles southwest of Jerusalem at the Elah Fortress in Khirbet Qeiyafa, the earliest known fortified city of the biblical period of Israel.
