The Pawnee believed that the Morning Star and Evening Star gave birth to the first Pawnee woman. The first Pawnee man was the offspring of the union of the Moon and the Sun. As they believed they were descendants of the stars, cosmology had a central role in daily and spiritual life. They planted their crops according to the position of the stars, which related to the appropriate time of season for planting. Like many tribal bands, they sacrificed maize and other crops to the stars.
