Is it possible Hell already exists here on Earth?

Those things you mentioned are just evil things that man made for himself on Earth. It isn't hell. Hell is much worse than that. It is the place where a person will or might go after living a life of those things you mentioned (evil things). Your question is very coincidental to today's Gospel reading. Luke 16:19-31 If you have time just read it. It says something about heaven and hell.

If life on earth is bad, Hell is much much worse. And i agree with the others when they say that the way we perceive hell depends on the life we lead or the trials we're facing in life. It may be hell for those who have less and are suffering too much. But one thing I'm sure of is that Hell isn't on Earth. :)

i think you could be right. i've questioned the same thing.

It depends on how one perceive hell, whether in context with the Bible and traditional beliefs or implications of what hell is. Based on religious tradition, hell is a fiery place of endless suffering and punishment, infested with demons, a place where wicked person is destined to go when they die. Many people have come to believe that we don't have to die to know what hell is as the essence of hell is already being manifested in today's world while we are still alive.

I've wondered about that too, actually, but if we're going by the Bible, I don't think so. Biblically, Jesus refers to Hell as Gehenna- a place of eternal damnation. And there are layers to Hell, the lowest being the Lake of Fire, where Satan himself will go. I think Earth is a sort of Limbo period and where you go after will be Heaven or Hell.
