IMHO, this is an invalid comparison because, in the case of the wine
in Cana, there is no evidence to the contrary: we don't have samples of the
wine, as simple as that and, if we were to find them, they would probably be
too contaminated to identify them or to ascertain anything about them. We
do have geological evidence and, in particular radiometric evidence (Oklo
natural reactors), that strongly suggest an old earth.
