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.
Hauran
There are records of settlements in the Hauran in the Ancient Egyptian Amarna letters and the Book of Deuteronomy of the Old Testament. The region was then known as "Bashān". Control of it was contested between the Aramean kingdom of Damascus and the Kingdom of Israel in the second half of 2000 BCE. It was ultimately conquered and pillaged by the Assyrian Empire, which held onto it between 732 to 610 BCE. Bashan later saw security and prosperity under Achaemenid rule; its settlements became better developed and culturally Aramized.
