Death of God Theology

The plausibility of Death of God Theology seems to rest on the apparently observable reality that God is not about.  Primo Levi gives one account.  I believe there was a hugely destructive earthquake in Spain in the 1600s which energised a certain critical spirit during the Enlightenment. (As always on this blog, more information will be welcomed).  These seem to be more the death of Man.  And I thought the bible was very clear in attributing this to the fall. This is the world without God.
