Cumulative Case Arguments: "Arguments for the existence of God (or some other complex claim) that do not consist of a single decisive argument but rather try to show that God's existence makes more sense than any alternative hypothesis in light of all the available evidence. Richard Swinburne, for example, presented a large number of arguments, none of which has decisive force. But since each argument has some evidential force, the cumulative case is alleged to make the existence of God probable."
