 All scientific knowledge is subject to later refinement, or even rejection, in the face of additional evidence.Scientific theories that have an overwhelming preponderance of favorable evidence are often treated as "de facto" verities in general parlance, such as the theories of general relativity and natural selection to explain respectively the mechanisms of gravity and evolution.Religion does not have a method per se partly because religions emerge through time from diverse cultures and it is an attempt to find meaning in the world, and to explain humanity's place in it and relationship to it and to any posited entities.
