Well one thing might be confusion about why creationists oppose evolution. It is not because of science or any reason related to that. the leading creationists are not morons who can't think straight either, their thinking is crystal clear, and they do have a very important reason to oppose evolution. Well actually two reasons, which both go together, they can be stated simply; doctrine and morality.
It has been stated all over the AiG website what the debate is really about. It is about a theological dispute within the Christian faith. Essentially how do we approach evolution? There are a great many Christians; both scientists, theologians, and laypeople who believe in both God and evolution. Many do not see evolution and religion in conflict. However the problem is that both sides of the extreme (bible-thumping fundamentalists and bible-burning atheists respectively) do see it as in conflict. The main problem for many is death and suffering. Young Earth Creationists at least hold to the belief that there was no death before Adam's sin, and being that the fossil record shows death and suffering long before sin they see this as an obvious problem for Christianity. Atheists such as Albert Einstein and probably Richard Dawkins who agree with the creationists' interpretation of the bible concur with this point.
This problem is a nagging problem for creationists and theistic evolutionists trying to convince creationists to accept modern science.
Is this true, is evolution truly the death knell of Christianity? Well luckily it is not Creationists have not given any proof that there was no animal death before the fall. In fact Psalm 104 seems to indicate there was death in animals before the fall.
Another biblical problem they have with evolution is the existence of Adam. Evolution teaches that humans share common ancestry with great apes so ultimately humans go back to apes not Adam. Creationists believe this is the death knell of Christianity, atheists agree (this particular quote comes from John Stear host of the site No Answers In Genesis):
“If evolution is fundamentally correct, then there was no Adam; no Adam, no fall; no fall, no atonement; no atonement, no reason for Christ to have died on the cross. If Christ died for no reason then he was not divine and Christianity has no basis in fact. Is there really any need for scientific proof in order to debunk Christianity?”If Adam doesn't exist then yes we do have a problem, I do believe in a literal Adam who is the genetic common ancestor of all people alive today (although some theistic evolutionists don't think he was the genetic common ancestor). Its possible he may have been Mitochondrial Eve's husband. Genetics has traced every human alive to day to a human common ancestor like the bible says. So their fear seems somewhat unfounded. There are many other scientific, theological, and biblical issues which must addressed though.
The second real reason for their rejection of evolution is morality, on their website in the Q&A Morality and Ethics section they quote G.K. Chesterson a 19th century Christian apologist on morality and evolution:
Darwinism can be used to back up two mad moralities, but it cannot be used to back up a single sane one. The kinship and competition of all living creatures can be used as a reason for being insanely cruel or insanely sentimental; but not for a healthy love of animals … That you and a tiger are one may be a reason for being tender to a tiger. Or it may be a reason for being cruel as the tiger. It is one way to train the tiger to imitate you, it is a shorter way to imitate the tiger. But in neither case does evolution tell you how to treat a tiger reasonably, that is, to admire his stripes while avoiding his claws.Basically what they are trying to get at is evolution leaves no basis for morality. Once you remove Creation you can do what ever you want. As shown in this illustration they see evolution as the excuse to throw the bible away and commit all sorts of sins which are at the center of social concerns today:
If you want to treat a tiger reasonably, you must go back to the garden of Eden. For the obstinate reminder continues to recur: only the supernaturalist has taken a sane view of Nature.’
As you can see here Answers In Genesis state that evolution allows for humans to decide moral truth which is a cardinal belief in humanism and therefore gives way to behaviors which they see as immoral.
Is this true, well their problem is that Creationist are confusing evolution with moral relativism, evolution being a natural process doesn't say anything in regards to morality or ethics or God or atheism for that matter any more then the theory of gravity or the laws of thermodynamics. Scientific theories are amoral. What creationists don't understand is that evolution is what you make of it; if you say evolution is God's method of creation and that we should obey the God of the bible that's what evolution is, a creation process. If you decide that evolution is a godless mindless process that has no plan or purpose then that's what is, if you add evolution to biblical Christianity you will get Christian morality, if you combine it with atheism you will get relativistic morality and make whatever you want of evolution. Carl Sagan thought evolution was a benevolent process and he had an adequate moral standard. And there have been atheists who have used evolution the opposite way to do evil as seen from the Christian worldview. Creationists cant seem to tell the difference between Atheism, Humanism, and evolution. which is much cause of their moral view towards evolution.
As stated before, Creationists are not stupid ad they are thinking very clearly. However science is not gong to convince them, there is plenty of science to address their complaint but what needs to be done is that Christians who accept evolution need to stand up to creationists and atheists and address the theological issues between Christianity and evolution. If we can show that Creationist theology is flawed then the creation/evolution controversy will end soon afterwords. Once the religious element of creationism is gone the pseudoscience will die soon afterwords.
