The coverup is necessary as disclosure will put all religious doctrines to the test, and noi doubt a number of the population will panic and cause mass civil unrest.
It seems highly unlikely that they don't exist somewhere. I wonder what they like it? It's probably something we'll never know.
We now don't have any proof for it. But seeing the immense universe the Scientists do believe that we are not alone in this Universe......
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.
