“Is man merely a mistake of God's? Or God merely a mistake of man's?” – Friedrich Nietzsche, based on his writing in The Twilight of the Idols.
Nietzsche’s first question is ontologically unanswerable. His second question is metaphysically unanswerable. The answers to these questions would fall into the category of matters of faith. Either you have faith in ontology and metaphysics, or you don’t.
