He brings to the forefront the importance of understanding how the notion of God evolved throughout history, in keeping with the human brain's development. He also shows how God and humans have fashioned each other in an attempt to understand and reach one another. Khan exposes the textual commonalities among Holy Books and shows how modern-day religions spring from previous religions.
