People are frightened by what they can't control, can't predict, and don't understand. That's why people invented gods to help explain unpredictable weather and other disasters. It works that way with people too. People want other people to be predictable, controllable, and understandable.
In which religion can you control or even fully understand your god?
Naturalism lends itself better to the idea that the universe is understandable and controllable are you sure we didn't invent it?
