The God in the movie Avatar is called Eywa.
Eywa is a powerful, interconnected consciousness that acts as a spiritual force and a guiding presence in the Na'vi culture. She is a manifestation of the natural world, embodying the interconnectedness of all living things on Pandora.
The Na'vi believe that Eywa created all life on Pandora and guides them through their lives. They communicate with Eywa through a spiritual connection called tsahìk, which allows them to access her wisdom and guidance.
Eywa is a central element of the Avatar universe, representing the balance and harmony of nature, and the Na'vi's deep respect for their environment.
