Christians-when judgment day comes and the good go to heaven and the rest of us go elsewhere?

what happens then? what was the point of it all? an experiment by god for gods amusement? is that it? all the war all the human caused misery torture famine and unspeakable horrors over all the long years,in the end was just a test to see if,with a minimum amount of evidence,we'd believe? can any religious person explain this to me in laymans terms? without the use of scripture or bible quotes? because theyre 2000 yrs old and i find it hard to derive any meaning or sense. ps this is a genuine question.
