I see you've been fed some extremely simple-minded lies about atheism. No, atheism is not "I only believe in things I can see." It's about evidence.
There is ample evidence that the sun exists when the part of the earth I live on is rotated away from it.
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.
