How come people so much experts on Hell

Hell does exist, What is hell,we see people dying of hunger, Blind , deaf, Lame people, beggars , war etc. all such things present on this earth are making the life hell. If hell does exist here in this world , then it might be present somewhere in the whole universe.On earth we are watching a sample only

I suppose that people know so much about hell even though they've never seen it is the same reason that you know that hell cannot exist. The answer is belief.

Hell its where Satan dwell... And Satan is an enemy.... As I, a Christian, Satan is an enemy.... We Christian has a constant war and battle with Satan.... Satan is the enemy we must know the information of our enemy, we must know where is Satan dwells, living or his headquarters.... And we must know Hell and fight Satan.... If we Christians don't know Hell we may not know that we are already at Hell so before its too late we must know Hell to save ourself.... But I am not yet an expert about hell, that's why I am here living on this world as a Catholic Christian to know the truth about hell....

Because our knowledge of what hell is was created by humans. I'm sure there're passages in the bible also that say something about an opposing afterlife to heaven. They don't know so much about Hell, they just have various beliefs about it's source, it's existance and the destination itself. it's because people created the idea of Hell that we have so many perceptions of it: i.e 'firey pits' 'Satan' 'slavery' 'torture for eternity' etc etc a human will assume that hell is a persons' worst nightmare. i guess it could be said, It's a directory method to try making sure your life is 'pure.' lol when opening up that discussion you made people confront that. Thanks btw i enjoyed that discussion ^^

No one is an expert on hell. There are people who are experts on their religions concept of what hell is, though. And I don't see what's wrong with that. What makes you such an expert to claim that it doesn't exist?
