Christian's loss versus atheist's loss?

I believe this is one of the main reasons that religion exists in the first place. Everyone is afraid of death and believing in an afterlife makes the idea of death easier to deal with. It is much easier to deal with a loved one dying if you believe that you will see them after you die. Everyone feels pain when someone they love dies, but some people use belief in an afterlife as a coping mechanism. For the rest of us, we just have to accept that we will soon be where they are- decomposing in the ground. There's nothing we can do about it
