It is technically possible that only those who do believe in Jesus never go to heaven. It is literally man made hearsay that actually has a better chance at being wrong than right. Nobody really has the answers but the evidence and reasoning certainly supports some positions better than others.
However, the evidence strongly supported a flat earth at one time but we know how that turned out. As humans, we can only make reasonable conclusions based on what we can actually know, which isn't much. It is best not to judge others since chances are strongly in favor of your judgment being wrong, which is why Jesus and others preached against doing this.
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.
