The religious practices of ancient oceania were based on polytheism and antinism.
The primitive peoples of Oceania did not distinguish the natural world from the supernatural world. Those people still did not have the courage to understand the phenomena of nature as the menstruation and the pregnancy as a natural thing, but as a positive work of the spirits.
In addition, these people also believed that supernatural powers roamed them and believed that war movements were negative influences of the spirits.
In short, these cultures attach great importance to the veneration of the ancestors and in nonhuman entities as a spiritual essence.
