I agree that scientists - and people in general - should not be too quick to stifle opposing hypotheses. In their defense, however, they probably view it as moving backwards into territory that was hard-fought to escape from (i.e., pre-evolutionary theories of God's direct intervention to specially create life on a young Earth).Additionally, it can be in effect a "science stopper" to say "God made it that way." How did the bacteria's flagellum arise? We can say, "Well, God caused it to be that way." But if we don't have that as an answer, we are forced to look for alternative explanations. It is this drive to search in new places that can result in new discoveries.
