I hardly think that Judaism is about truth claims of ANY sort. As I've said before, G-d is a "given" (i.e. not a "belief"), and belief in Truths (or anything), is always secondary to the action one does in "support" of these Truths. It wasn't even until Maimonides came along, in the 12th century, and in response to Islam, actually formulated our Thirteen Articles of Faith (and "Faith" is really an inapropriate word here). We had gotten along fine for millennia without them being codified...
