Well the demiurge is the creator of this world. Jews, Muslims, and non-gnostic Christians identify their deity as the creator.
The demiurge is actually something akin to "Lord Shaper" though, right? He is not, strictly speaking, identified with ultimate reality. I think you've identified a disagreement between Gnostics and Christians/Jews/Muslims, but most (though not all) would probably identify God more along the lines of the Monad, although they also agree that the God of the Tanakh is the same as the Absolute one god.
There are Jews and Christians, at least, who disagree and think that God is more artisan/shaper than creator ex nihilo (or via emanations, if you prefer). But they are a minority.
