The priests kept the records of the government and were also in charge of religion. They used oracle bones to predict the future by interpreting cracks produced by the bones by applying heat. They carved questions and their answers onto the bones. The religion in the time of the Shang dynasty was based on ancestor worship and a worship of many gods; the main god was known as " Shang Ti " or " Lord on High ". " Shang Ti " was the supreme god over the other gods such as the wind, the sun, the rain and many more.
