According to tradition Xi Ling Shi (also called Xilingshi, Xi Lingshi, Leizu, Lei-tzu, Si Ling-chi, Hsi Ling Shi) was a Chinese empress who reportedly discovered silk-making in the 27th century BC.
Xilingshi invented silk.
Xilingshi, also known as the "Xiling Stone," does not have a historical basis for existing 5,000 years ago, as it is often associated with modern interpretations or fictional narratives. If you're referring to a specific ancient civilization or artifact, more context is needed to provide an accurate answer. Generally, the study of ancient civilizations focuses on well-documented cultures like those in Mesopotamia, Egypt, and the Indus Valley during that time period.
