Right. So objectively, the word "meaning" has no meaning. There is no objective concept of meaning.
"What's the meaning of life?" seems to be a question that tries to get at the nature of things from the outside perspective. The answer is that there is no answer. We can't see the outside perspective.
Maybe there's an objective "meaning of life", but we'll never know. Practically, there is no "meaning of life", only an interpretation -- our own meaning.
But that means that we're alone. That's the scary thing for most people.
