We will exist again after we die, but not in this world. I will be waiting for you all in heaven.
This is the misconception of most people. Everyone goes there but not for sure, there really are those people that are bound to be there but not everyone will be there after death.
Different theories does exists that after death you come back on earth if you happen to go to hell. But if you go to heaven than you are away from earth. Different religions have different beliefs and nothing can be said as complete black and white. Do your best when you are on earth simple.
Once a soul goes in hell, it's said that there's no coming back and that's the same for heaven. So after death, it's about perish or greener pasture.
