People will die because nature works this way. Of course if humans find out ways to live longer (there are experiments, biological treatments) then this world will change a lot. But well... Everyone did not exist before born - if death is similar, it probably does not matter for us humans. If there are not God, Gods and something else then our lives could be pointless. You can die tomorrow and you will not find out it. You will not know that your family members or friends (if you have) will be sad. It is hard topic but you know.

I have no idea what you are trying to say
