This question was posed by Doc_M in the previous installment and looks like this verbatim: 

"Assume first that atheism is True.

Consider the following:
It is inevitable that relatively soon you will die. You will cease to be and--not existing--will remember nothing that you have done. It is also inevitable that everyone and everything that remembers what you have done or who you are will also die relatively soon. Even if you and a million generations after you lived a trillion years and remembered you, they will inevitably die as well, so ultimately you and all you have done will be forgotten as if it--and you--never happened to begin with. This implies that the only way for anyone to matter at all is to live for eternity... real eternity. Otherwise, even after unimaginable ages, we will all pass away and will have never mattered. So, "I live to enjoy life" and "I live for the betterment of humanity" and "I live to pass my genes" all are moot, since all will be lost and forgotten ultimately unless eternal life is achieved.

That said:
What is the point?
Can you imagine not existing anymore?

Considering the above paragraph, why does anything at all, including morality, matter at all?"
