Not to get into a long, draw out post about it, but Christianity has butchered what the Bible actually says about Heaven and Hell. Much of that butchery comes from the 1611 KJV which erroneously translates a simple concept in either Hebrew or Greek. The Bible never says that we go to heaven when we die, only paradise. Revelation 21 defines paradise as being on New Earth, not Heaven.
Secondly, the term for heaven in Greek is ouranós, and it has three different meanings:
1. God's place of dwelling.
2. The cosmos.
3. The sky.
You have to look at each verse in context to understand which of the three it is referring to.
Lastly, Hell is a butchery of four different terms that were lumped together. Those terms are:
1. Sheol - Hebrew for the grave
2. Hades - Greek for the grave
3. Tartarus - a place of punishment for rebellious angels
4. Gehenna - a place of burning
The Church uses the concept of Hell as a place of burning and eternal torment for the purposes of fear mongering and guilt trips. It is utter nonsense.
