In a sence the person does live after death. The person is talked about and remembered long after he passes away.
Not just talked about or remembered. A person could pick up a piece of garbage and put it in a proper container. This could be witnessed by a child who, with other inputs, devotes their life to cleaning up the world. You live there too, even if your name and action are completely anonymous and only a small factor in other's accomplishments. The butterfly affect applies to souls (as I see them [influence]).

But really, I use 'gesundheit' instead of 'God bless you' toward people that sneeze, and even I don't think that 'Rest in peace' is atheistically contradictory.
I also 'gesundheit', when a need for obligatory gesture owns me.
