Brontolatry

Brontolatry, also known as ceraunolatry , astralatry , tonitrolatry , and fulgolatry , is the worship of thunder and lightning. Lightning and the accompanying thunder is triggered by Greek god Zeus or Norse equivalent Thor. Lightning was created as a weapon to battle demons and dragons. The idea for creating lightning only out of dark, gray clouds is that dark clouds would darken the area in order to attract more evil entities to be battled with lightning. Because lightning is used to kill the evil entities, lightning can also be used to kill unsuspecting people when lightning god wrongly uses it to strike people or even as a form of punishment or curse.
