Do Abrahamic faithfuls know that billions of Hindus don't make the Hindu god, Vishnu, real?

Yes. That would be appealing to the populace. I don't know what but I know the Abrahamic God is the Only True God.

My belief in God is not based on the billions of other Christians who believe in My belief in God is based on s word and the work He has done in my life.

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.
