Depends on your theory of heaven and hell.

I believe in the catholic faith, all those who reject god but live good lives go to limbo, which is a peaceful, but sad place. Some other christians believe that all good people go to Heaven while others have non-Christians go straight to hell.

Some others believe that different gods have different kingdom's, so the Christians believe they go to yahweh's Kingdom, while Vikings believe they go to Valhalla, and those blue Aliens from Avatar believe they join the ecosystem.

My own personal opinion is that any real example of heaven or immortality is in the minds of the people of the world. In this way, people like Churchill (not the nodding dog) is alive in the minds of the people who remember him and his duties during WW2, unfortunately, this says to same about a couple of other figures during that period too. Death itself is more returning back to the earth, in a less pleasant way, if you get buried, you become plant food, in the ecosystem we call life.
