Hadean
The Hadean () is a geologic eon of the Earth pre-dating the Archean. It began with the formation of the Earth about 4.6 billion years ago and ended, as defined by the ICS, 4 billion years ago. , the ICS describes its status as ""informal"". Geologist Preston Cloud coined the term in 1972, originally to label the period before the earliest-known rocks on Earth. W. Brian Harland later coined an almost synonymous term, the "Priscoan period", from "priscus", the Latin word for "ancient". Other, older texts simply refer to the eon as the Pre-Archean.
Prehistory of the Levant
The urban development of Canaan lagged considerably behind that of Egypt and Mesopotamia and even that of Syria, where from 3,500 BCE a sizable city developed at Hamoukar. This city, which was conquered, probably by people coming from the Southern Iraqi city of Uruk, saw the first connections between Syria and Southern Iraq that some have suggested lie behind the patriarchal traditions. Urban development again began culminating in the Early Bronze Age development of sites like Ebla, which by 2,300 BCE was incorporated once again into an Empire of Sargon, and then Naram-Sin of Akkad (Biblical Accad). The archives of Ebla show reference to a number of Biblical sites, including Hazor, Jerusalem, and a number of people have claimed, also to Sodom and Gomorrah, mentioned in the patriarchal records. The collapse of the Akkadian Empire, saw the arrival of peoples using Khirbet Kerak Ware pottery, coming originally from the Zagros Mountains, east of the Tigris. It is suspected by some  that this event marks the arrival in Syria and Palestine of the Hurrians, people later known in the Biblical tradition possibly as Horites.
