The native people had their own religion in which colonists after the war started to assimilate. This religion is called Atomicism. It’s more like a series of spiritualistic and cosmologic beliefs. They believe in the theory of multiverses. They believe each person is its own world; it’s all about perspective.

They believe that each human eye is a black hole, that’s why they burn the body when someone dies, to prevent the black hole to expand. Also, they believe when someone is blind is because you are being attracted by your own two black holes, so they kill blind people. They don’t have a specific god, they only have many beliefs that make up their own religion.

These people are very compassionate, but they defend too much what belongs to them, as they respect much what they are, including creatures and plants. However, they also believe that everything is destined for a specific function, such as cats are destined to provide food and skin for the naaroahan species. Nor do they have specific rituals to worship gods (they don’t have) or objects. As mentioned above, their religion is based on beliefs and behaviors that the entire population follows and makes them a united community. 

Maybe the majority of these beliefs, were brought by the humans in ancient times, and they were changing among history, because colonists saw many similarities with their own beliefs, for example, the theory of multiverses, for the colonists this was a scientific theory but for the natives, this is a religious belief.
