It sort of comes off to me as a lighter way of asking how you can be a moral person without the threat of eternal suffering in the afterlife (not to suggest that you actually mean that).
I consider myself agnostic, practically an atheist, I just don't really like associating myself with the "hurr durr sky daddy" types, I think religion and the idea of a creator are valuable to help people cope with situations which are totally out of their control, but I can't really relate to needing a creator to give me purpose. I give myself purpose by doing and supporting the things that I feel are right/important.
I don't think existence needs any overarching purpose offered by a creator, it's fine that everything is ultimately meaningless. If anything I find it relieving since it also means that our failures also only have as much meaning as we ascribe to them.
