Where hindu gods like BRAHMA,VISHNU,DURGA,KALI MATA,SHANI DEV,SURYA DEVA,CHANDRA DEVA live? did they exist?

No, these are inventions from the Hindu imagination. There can be only one God who has the qualities of God--omniscience, omnipresence, and omnipotence. For a similar reason, we have to reject the idea of a multiverse, for if there were other universes, no universe could be universal.

Sure, if you believe the holy books written about them, they really exist and millions of people have seen them. And if it's written in an ancient book, then it must be true, right? There's no way some ignorant and superstitious ancients would just make stuff up!

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.
