The earliest ancestors of the Shi'Ji were estimated to have arrived in the Land of the Great Spirit nearly 57,000 BCE. According to Shi'Jian legends and religion, the early ancestors of the Shi'Ji had evolved to a new plane of existence and left the planet but before leaving had brought Shi'Ji to the Mksi'Tskin'Stsu (Land of the Great Spirit), to live and continue human life on Pangam-Pangat in a new era. Then the evolved ancestors left the planet to join the Spirit People in the stars.
