According to Father Bill Stoeger, a Catholic priest and a cosmologist at the Vatican's Observatory in Arizona, who also holds degrees in theology and philosophy:
We learn a little bit about God from scripture but a lot about God from creation -- which includes ourselves, nature, art, the beauty and goodness of the universe and its tragedy.
Speaking of the faith of those who believe in the literal account of creation as described in the Book of Genesis, Stoeger goes on to say:
Their theology is very primitive and they have no adequate means ... to integrate their (religious) tradition with the real world.
