Pretend my child just died. Now, from an atheist's point of view, console me in my grief.
I am incapable of accuratedly knowing what an atheist would say. Perhaps something like..’be thankful that your child is at peace, or is no longer in pain’...something like that. Although, an atheist may not care how you feel, as they know it is the child that died, and you have to deal with these things in your own best manner.
