Well said--although I'd prefer to live foreever, or at least a very, very, very long time. But I don't believe things just because I would like them to be true. You can't make deals with existence, such as "If I believe X, then I'll get to live forever."
And for the audience: Morality can only come from each individual, since each individual must decide for himself what is right and wrong. Even if you think your morality comes from a transcendent source, it is you who must decide that your moral code comes from a higher authority, and it is you who must decide to live by that code (whether for that reason, or for some other.) There is no getting around that fact.
Morality and all of its associated ideals are rooted entirely in the presupposition some higher power defines what is correct for human behavior.
Good & bad, right & wrong, etc., etc., ad nausea; are all inherently religious ideals.
