Let's go through this slowly, so we are clear. "Meaning" is of Old English maenen (and related to German meinen), "to intend, to indicate, to signify."
Precisely, to indicate = to give meaning.
That the starry firmament or the moral/childlike wonder within are said to give ontological purpose beyond oneself is a premise of Godliness, eternal purpose.
Cognitive dissonance is a (usually) bifurcate gnosis: "this and not-this" at the same time and in the same relation, aka the law of non-contradiction: ~(p + ~p).
While the human is able to handle this dissonance, it is psychologically discomfiting for some. The person who believes that God is not speaking, even through the starry heavens' fine-tuning, and who indicates, Sartre-like, that one may choose signification (e.g., based on Kantian universal human values, thus the golden rule of Categorical Imperative), is not experiencing cognitive dissonance unless she has a subconscious premise that God should speak and doesn't.
Again, to indicate, to gesture, is to give meaning. (This is how Boolean logic is developed, for example.) To claim that God does not gesture is to claim illogically, as to know God is not speaking or indicating requires Omniscience and Omnipresence, of oneself.
