Human beings have inhabited the Armenian Plateau and Caucasus Region since over 100,000 years ago. Little is known of them, however, drawings in caves and on rocks attest to their existence. The area, situated between some of the Old World's major water ways, is generally considered the cradle of civilization. Archeological and historical facts point to the development of civilization in the region with the formation of the Urartu kingdom around 980 BC. The first mention of Armenians in historical writings is found in inscriptions at Behistun, near the city of Kermanshah in modern-day Iran, which date to 600 BC. The legendary founder of Armenia was Haik, a chieftain who called on his kinsmen to unite into a single nation, thus forming Armenia. Ararat was the mountain around which was centered Urartu and subsequent kingdoms, and is still considered sacred by the Armenians. The original Armenian name for the country was Hayq, later Hayastan, translated as the "Land of Hayk", and consisting of the name Haik and the Iranian suffix '-stan' (land). According to legend, Haik was a great-great-grandson of Noah and according to the tradition, he is the forefather of all the Armenians. Mount Ararat, a sacred mountain for the Armenian people, rising in the center of the Armenian Highland as its highest peak, is traditionally considered the landing place of Noah's Ark.
