I would report him, gnu, but I doubt it would do any good. ;-)

"A miracle" is just an expression for an unusual occurence that astounds people because they really did not expect it to happen that way. It's useless arguing over stuff like that and trying to invalidate another person's way of expressing their shock, surprise or relief over some incident. You won't change anyone by doing it, and it won't prove you're smarter than they are either.
