The Greeks may have had more sense that we do! But I note another interesting point, which is that none of the arguments we've seen so far that the multiverse is a scientific model even mention string theory, so they could have been formulated as soon as humanity asked the question "why does the universe support life?" and did not immediately invoke gods. That kind of shoots down the idea that somehow the idea emerges naturally from string theory and so if the latter is science, the former is too. Maybe we just haven't heard their best argument yet.
