In the open source Religion 2.0 and Evolution Spirituality found at Universe Spirit, miracles that defy the natural laws are treated as a personal issue of subjective faith. Miracles may not be used as proof of spiritual authority or spiritual truth for anyone other than the individual experiencing the miracle even if the miracle has been subjected to rigorous scientific investigation. This is because even in the most rigorous of scientific investigation although the fact that an event has occurred might be ascertained with a high degree of certainty, why or what caused that event to occur is far harder to discern, especially when a spiritual cause is being assigned or attributed to that event.
