The Book of Genesis is considered to be a composite narrative containing a great many early Hebrew traditions, some of which bear evidence of having evolved from more primitive myths. The hymn to the sun. or Great Hymn to Aten differs considerably from this, but bears a remarkable similarity to Psalm 104. Not only does Psalm 104 have many similarities to the Hymn to Aten, it contains references to the sun that would be hard to explain other than by reference to sun worship.
