A son of Kush (Kish) was Ramah (see Genesis 10), for whom was named the river Ramah of northern Arabia, today a wadi called Batin which though during the Ice Age when Ramah was there flowed strong down into the Shatt al Arab river, their confluence on the bottom of the Persian Gulf since the end of the Ice Age. Kush and Ramah sailed on down the Shatt al Arab river then beyond to where they built Kushasthali, submerged in the Gulf of Kutch of India since the end of the Ice Age circa 1500 b. c.
