 This is the time of the agricultural transition and development of farming economies in the Near East, and the region's first known megaliths (and Earth's oldest known megalith, other than Gobekli Tepe, which is in the Northern Levant and from an unknown culture) with a burial chamber and tracking of the sun or other stars.In addition, the Levant in the Neolithic (and later, in the Chalcolithic) was involved in large scale, far reaching trade.Trade on an impressive scale and covering large distances continued during the Chalcolithic (c. 4500–3300 BCE).
