If a house falls down from termite damage and kills someone, science will be able to tell us how the termites caused all the damage, and the formulas involved in how the person died, as well as what injuries caused the death and what were postmortem or non-lethal. It, however, can't tell us why it happened to that house, or why it happened to that person. Religion can tell us why that house fell and killed the person, perhaps they were cursed by a witch, or greatly angered an ancestor, who summoned the termites to destroy the offending house and person. It however, can't tell us how it happened.
The two would work well together so easily, if only people stopped trying to encroach one into the other.
