I particularly liked how you explained some of the concepts in the second part of your comment. But about the last part, I tend to prefer a slightly (or vastly) different way to put it: "meaning" is a human concept, it only makes sense in that context. Searching for universal meaning that "transcends humanity" is a contradiction, it doesn't make sense. The conclusion is the same you were explaining, to look for meaning in our own stories, in our own terms, in our own reason, feelings and perspective.
