三皇五帝
The ancient Chinese historian Xu Zheng () in his "Three Five Historic Records" dated the creation of the world by Pangu 36,000 years (2 x 18,000) before the reign of the legendary Three Sovereigns and Five Emperors. The date of the "Three sovereigns" is fixed at 3000–2700 BC and therefore dates the creation about 39,000 BC.
