The Sun as a Guide: Inventors waited for the sun to reach its highest point in the sky and declared that exact moment to be noon.Using Sundials: Ancient people used sundials to track the sun's shadow. They marked where the shadow fell at noon, and then split the rest of the daylight into equal parts.No Single Creator: Time was not invented all at once by one person. It evolved slowly over thousands of years through natural rhythms like sunrise, sunset, and seasons.
