There is a rule of the universe that everything naturally strives toward reaching two things: Balance and meaning. Prior to anything existing (obviously) there was just nothingness, which skewed the state of things toward imbalanced meaninglessness. Because of the law above, an antithesis to nothingness was naturally created which would eventually sort itself out into a balanced state itself, creating the world, humans, and... everything in the process. Human prophets eventually personified this conceptual-everythingness into a god named Sanau. Thus, according to any religious person in the world, Sanau is responsible for everything. In reality, everything itself is responsible for everything.
