 One way to distinguish between science and religion is the claim that science concerns the natural world, whereas religion concerns the supernatural world and its relationship to the natural. Scientific explanations do not appeal to supernatural entities such as gods or angels (fallen or not), or to non-natural forces (such as miracles, karma, or qi). For example, neuroscientists typically explain our thoughts in terms of brain states, not by reference to an immaterial soul or spirit, and legal scholars do not invoke karmic load when discussing why people commit crimes.
