Just because something takes a proper grammatical form doesn't imply it has any correspondence to the real world. "A horse has four legs" and "schmorgles are borgles" are both grammatically correct sentences but only one has discernable empirical value. I can go out and find you a horse with four legs, can't find you any schmorgles. As to moral statements taking the form of true or false statements, again it does nothing to proof that they are in fact true. the reason for this is psychological. Saying "torture is wrong" has just the same semantic content as saying "Ewww, torture!", or alternatively the command "do not torture!". The reason why we frame it in the language of moral fact is obvious, because it's useful to frame commands as being embedded in a moral framework if one wants to universalize and impose them. The language of moral facts is a a way to rationalize moral commands. This is completely equivalent to religious truth claims. Religions have elaborate epistemological concepts about heaven and hell, afterlife, even a sort of physics of supernatural spaces. Does that conjure them into reality, merely because they are able to talk about them? No of course not. Does it follow that the trinity has any truth or false value merely because someone talks about the concept? Does Middle Earth exist because I can make propositional statements about Hobbits of the same form I can make about particle physics? No. And as to the last part, yes science is to some degree a game of this very same sort, although it varies drastically by the kind of science you're doing. There's non-normative science largely concerned with making empirically verifiable claims. Science that tries to make normative claims does not progress for this exact reason.
