There's no evidence for other universes besides this one and if there were other universes they could all support life and/or intelligence of some kind for all we know and all have been created by God seeing as they are all effects of a cause one single eternal cause can cover all effects that ever occur. The fine tuning argument just points out the contingency, complexity and rational comprehensibility of the universe, it isn't really a seething chaos even if it has some unpredictability.
Come all ye faithful joyful and triumphant.
