isn't the problem usually not with "appearance of age" but rather "appearance of events happening that never happened; or appearance of objects existing that never existed?"
Is the "object that never existed" in this case: a star, which
had to have (by some reckoning) spatial (x,y,z) coordinates, composition and magnitude; which existence is presumed from the residual glowing gasses?
I think its a distinction without much difference. Additional terms have simply been introduced, which seem to demand even further rigor in justifying the observed phenomena.
All these aspects do is insist on some prior ontological criteria, to justify what may be observed in the present. An adult Adam "presumes" the events of the life of a child-Adam, which never happened according to special creation of the first man. The same is true for Eve.
No one has suggested the Bible proposes there were drawings of Adam's "parents" tacked to the nearest tree; nor their bones that could be dug up from a nearby "graveyard," containing numerous generations of "ancestors." And yet, those putative "bones" are actually called for by theistic evolutionists. And the fact the Bible doesn't mention the bones makes its story myth to them.
So, either something is missing, or something is present, to falsify the story as it is presented. The heavens, with all its wonders, is presented to man as part of the scene, the givens of the starting conditions. The vastness of space is actually
taught to man (and the consequent superior immensity of God to anything he created) by including "evidence" of a supernova, which light would by natural means take unfathomable ages to arrive. The idea that there "had to be an exploding star that first grew into the mass that finally exploded" is all presupposition. It isn't required by the narrative of what Genesis says took place.
