Time and space is contained in the universe so God cant be of size and there can be no when outside of space-time.
Just because the universe did not exist before God created it, does not mean that God was smaller. The bible says that God is and was always the same. Psalm 102:27 but YOU ARE THE SAME, and your years have no end.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
