It’s inevitable that anything invisible tends to be supernatural in the sense of being uncertain about who or what causes it. Who can be trusted and who can’t. In fact, such beliefs used to be the norm in Europe and they’re very much so still in Africa. (I actually consider the religiosity of 21st century Africa to be comparable to its early modern European counterpart as it gives a better idea of what the latter was like.)
Even today there’s still a belief in the supernatural but in the developed world, it’s generally associated with either fundamentalists or fringe groups if because the belief in the supernatural in general declined. Secularism more or less takes place in times of certainty and safety whereas poorer countries rely on religion to make sense of suffering and misfortune. Not necessarily good or bad.
But that when it comes to misfortune, it can be easy to be wary but also a need to find something or somebody to rely on.
