Science cannot be done without the assumption of non-intervention. Science is looking for regularity.
There is a certain arrogance among those who claim that the intelligent design group or the creationist group are not scientists because they do not adhere to random, unguided evolution. It is the equivalent of traditionalist Catholics denying the validity of the Eastern Orthodox or Anglican priesthood or hierarchy because those churches do not acknowledge Papal supremacy. To some, it appears that whether one is a scientist or not is dependent on their metaphysical views, not their credentials.
