Genèse 9
"12God added... :
'13I set my bow in the clouds... 16With the bow in the clouds, I ... will remember God's everlasting covenant.'
17God said to Noah, 'This is the sign of the covenant I have made between me and all the creatures of the earth.'"
Let's do a grammatical analysis of verses 12, 13 and 16. The use of the first person in verse 16 implies that the God who speaks is split into a second who, within the speech of the first God, evokes His covenant. This first God, of whom the rainbow is the most beautiful manifestation, is the Sun God. The second can only be the living Egyptian God: the Pharaoh Akhenaten. He wrote these verses identifying himself with the sun-god Aten, of whom he is the earthly incarnation.
The fact that God allies himself with all creatures shows that He is universalist and suggests the abandonment of blood sacrifices. This is not the same God as in Genesis 15 and 17.
This God is obviously a human invention; it is the God of the monotheistic Pharaoh, Akhenaten.
