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.
Proto-Sinaitic script
Proto-Sinaitic, also referred to as Sinaitic, Proto-Canaanite, Old Canaanite, or Canaanite, is a term for both a Middle Bronze Age (Middle Kingdom) script attested in a small corpus of inscriptions found at Serabit el-Khadim in the Sinai Peninsula, Egypt, and the reconstructed common ancestor of the Paleo-Hebrew, Phoenician and South Arabian scripts (and, by extension, of most historical and modern alphabets).
