The Arrernte people's creation story tells of ancestral beings known as "Dreamtime" or "Altyerre" creating the land, animals, and people during their travels across the land. These beings left their mark on the landscape through songs, stories, and rituals, forming the spiritual and cultural foundation for the Arrernte people. The creation story emphasizes the interconnectedness of all living beings and the importance of respecting and caring for the land.
