The bible was written by flawed humans. A story to keep humans from doing horrible things to eachother. Everyone interprets the bible differently, and this is clearly obvious. It was humans attempt at passing some morals on to others. In such brutal times, the only thing that could get through to people was the fear of some horrible shit happening to them by a powerful evil monster with his own torture dungeon to keep you, and being good would be rewarded with heaven.
Passing morals onto dumbshit people is good, taking these crazy-ass magical stories as anything but a crazy-ass magical story used to instill fear apon a developing world of savages is your own poor judgement or the poor judgement of the people that forced all this bullshit into your young developing brain.
Does "God" have anything to do with the "bible god" or whatever scripture you have been raised with? Doubtful, as humans have proven themselves to be liars. We are at a point that humans can be quite good and moral without thinking you "need" to be for fear of eternal damnnation.
I am generally a good moral person that puts others before myself. I feel, whatever happens to me when I die is the same thing that happens to every human of every religion, no matter how deep their faith.
Can I prove it to be true? Of course not.
Can anyone prove it to be false? Of course not.
