If scientists knew how to deal with the issue effectively, it would not be a such a growing threat to science! Unfortunately, it is and their resistance to the religious reaction trend is ineffectual.
The "Born Again" claim that "living beings are too complex to have arisen by chance." But does "chance" have anything to do with evolution? We in science should know that everything is an unending chain of cause and effect. "Chance" is just that which we do not (yet) understand are the causes.
Unfortunately, too many scientists don't get it, however. In his Burguess Shale book, Gould attributed the evolution of pre-Columbian life forms to "luck" or "chance" and showed a "Creationist"-Intelligent Design way of thinking. Such "science" is a form of mysticism, not science.
The "Born Again" also claim that "Evolution is just one theory and not the only one." Again, scientists are unable to effectively rebutt this because they themselves call it a "theory." Since they do not know everything about evolution and cannot, therefore, prove it to be "The Truth," it is not, therefore, "fact" and so, on and on. What confusion! EVERYTHING we believe is "theory" in that none of it is absolute truth. All of it is more or less accurate or inaccurate. We can never know everything about anything. All the science we use to improve our environment is all theory and in various stages of being made more accurate. It is not static, and, hence, never "proven." It is all ultimately certain to be made more accurate and, hence, more useful to us. We will never know eveything---as the old religions claim THEY do.
So, the theory of evolution is not "truth" but it is far more accurate than the "Alternate theory" (the obsolete, Biblical story) of Creation.
In other words, scientists so poorly understand their own system that they give the enemies of science all the ammunition they need to humiliate science and put it on the defensive.
