A fool has said in his heart "there is no God" There's no proof .. it's in their dreams.
I think you are posing a question that you do not understand. If you understood what you are asking you would have sought evidence rather than proof. Also you would comprehend that proof does not require the adjective 'empirical'.
Finally, you would know that not all scientific evidence must come from an experiment.
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.
