In many cultures, little conceptual or practical distinction is made between “natural” and “supernatural” phenomena and the very notions of "religious" and "nonreligious" dissolve into unimportance, especially since people have beliefs in other supernatural or spiritual things irrespective of belief in gods.
Many societies lack a clear distinction between natural and supernatural occurrences, blurring the lines between religious and non-religious beliefs. Even when individuals believe in deities, they often hold onto other spiritual or supernatural ideas.
