I thing the interesting issue of living after death is retained as a secret until doomsday.
But i m sure there is somewhere for people after their death. But it's completely different with what i think. I've never been there so can't explain what will be happened there.
Some people that were nearly to death said that they saw a long tunnel with a light at the end of it. I think its a strong cause for existing somewhere after death.
Anyway you don't need to see with your eyes, but you can see it with your heart.
