Other scientists have argued, however, that since science has not definitively disproved the existence of God, it does not necessarily contradict religious belief, even though explicitly theistic explanations for the origin and development of life may be unnecessary. Those who advance this view typically portray science and religion as such distinct enterprises that their teachings do not intersect in significant ways. They also usually deny that theistic religion properly understood makes any factual claims about human or natural history; its claims are only about morality and meaning.
