@kennethamy,
Okay here's a definitive answer.
In those contexts where "the age of celestial objects" is a
matter of concern i.e. in arguments about biblical statements, or the retrodictive and predictive
modus operandi of (most) scientists it "makes sense" to say "the moon is older than the age of man as a species". Such a statement WORKS in that it satisfies the communicative needs of those particular interlocutors. But to demand " the truth" of the statement is totally without meaning when discussing the concept of "existence" , because that already
assumes "existence" is independent of the actions and physiology of observers. i.e. "Non-contextual truth" is meaningless.
If you want to call yourself a philosopher you cannot make that assumption. especially when some contemporary scientists question such a notion themselves.
Now having given you a definitive answer , why don't you surprise us all by indicating that you understand it, rather than countering with some irrelevant verbiage which amounts to sticking your fingers in your ears and singing ?
