The beginning of the ancient stone industries did not depend on a specific technology for flint industries, but rather relied on the ability and knowledge of the manufacturer and the availability of raw materials. While Middle Paleolithic industries relied on the same technology to produce flint tools. With the beginning of the Upper Paleolithic period, modern man grew up and was able to control large geographical areas that were not previously inhabited, and he made stone and bone tools of various sizes, especially the production of small blades, which enabled him to invent and use the crossbow.
Archaeological excavations over the past century have searched for Early Bronze Age civilization in dozens of human settlements in Jerusalem, Tell Al-Far'a, Jericho, Tell Al-Jazar, Tell Al-Sheikh Ahmed Al-Arayni, Tell Al-Jazar, Tell Al-Tall, and Tell Al-Nasba. The first cities of the Early Bronze Age were not fortified and construction in them was generally simple. In the second phase of the Early Bronze Age, walled cities appeared, including public buildings, palaces, and temples, in Khirbet al-Karak, Tell al-Fara’a, Tell al-Tall, and Tell al-Mustaslim.
