The Son of Man died ן
The final nun ן is a nun נ which is turned below the line. It is the Son of Man (the nun) in death. It looks like a larger vav ו. It retains it's meaning as the Son of Man because it is a nun, but it indicates that through the death of the Son of man there was a larger distinction, or clarification than even at creation.
After creation man still did not understand that God alone was God. Through the cross, the Father is made known through the works of the son.
