Science v Creationism
Hi everyone. I keep popping back here every now and then to see what’s going on, and I have noticed that the same questions about science and creationism are continually posted and answered now, as they were when I first came here. I used to answer some myself but I’m just not that regular in ex-field service! The other motive I have for this post is that I have noticed that certain posters, who, although are probably genuinely trying to help, truthfully don’t know what they are talking about. They are answering many of these questions and being given a lot of credence. So, I thought I’d make a kind of definitive post on the subject of science and creationism (if anything so generalised can be called definitive!) so that the many people who genuinely attempt to answer these questions don’t have to keep answering the same questions over and over again. It will be just easier to point to this post. Please bear with me as I continue to add to this post over the coming months, because even though this is just an overview, I will be covering a large area of empirical knowledge.
I request that you do not comment or post on this thread as it will eventually become quite long enough as it is as I continue to add sections, and I don’t want it to become any more difficult to read than necessary as it would be were it interspersed with lots of comments. For comments and "bttt’s" please use the separate thread "Comments on Science v Creationism" that I have started here:

I intend to avoid being over technical and write as often as I can in a generalised, easy to read manner, and, in particular, I will write without references, as this isn’t meant to be a formal dissertation but a helpful overview to those with a general interest in the subject. Also, the fact that there are about a thousand references has something to do with my reluctance to type them up! But for those who are interested in checking for themselves, and are interested in a really in-depth review, please refer to "Science and Earth History by Arthur N. Strahler", which I will be using to walk through an overview of the subject. I have recommended this before but I now realise that few will ever read it due to the cost. A less technical read, and substantially cheaper, would be Scientists Confront Creationism, edited by Laurie R. Godfrey, which, in my opinion, represents popular science at its best. Also, an excellent internet resource is Alan F’s site at: http://www.geocities.com/osarsif/index2.htm
Introduction.
Firstly, I think it’s a bit of a misnomer to say Evolution v Creationism because although science is divided into different disciplines, for obvious reasons, these different disciplines often overlap. Physics makes use of mathematics, for example. In this way science has become like a kind of tapestry with all the different disciplines contributing to the whole. Moreover, creationists often quote from many different scientific disciplines, so I am calling this Science v Creationism.
But what is science, and what isn’t it? Imagine there are two mountains representing two ways of knowing, between which lies a great gulf. One mountain represents the Belief Fields, which do not require observation of the real world to validate them. On this mountain you can find appreciation for the beauty of nature or art or belief in the supernatural. The second mountain represents the Research Fields, which do require input from the real world. On this mountain you can find science and the humanities.
We are not saying one is valid and one is not, just that they are different and serve different roles; there is no need to reconcile the two for they are not in opposition, they are just different. Spirituality, not science, can provide comfort to the bereaved through belief in an afterlife, for example.
In real life this illustration works out thus. I think the Mona Lisa is beautiful. I think the Mona Lisa is ugly. Because these statements lie on the mountain of belief, both statements are valid in themselves and do require validation from facts or measurements from the outside world. However, consider this statement. The Mona Lisa is three centimetres wide and seventy centimetres tall. This is not a subjective or belief statement, and this statement lies on the research mountain because we can go and measure the Mona Lisa and a definitive answer can be given as to whether or not it is so. On the one hand the mountain of belief requires no measurements from the outside world to be validated: on the other hand the mountain of research does require such measurements to be validated.
There is only tension between the two when, say, a religion, uses are rather abuses science to give itself credibility or to try and show that science supports it’s religious beliefs. This can also be dangerous to the education of the people who are taken in by this as they become confused as to the difference between science and pseudoscience.
So when you hear someone say Science isn’t valid because it excludes God as an explanation for phenomena, you will know that they do not understand that by definition science excludes knowledge fields that cannot be validated by input from the real world. The concept of god, like the concept of art, simply isn’t scientific. It’s an oversimplification but you get the idea.
Truth. Science doesn’t or rather shouldn’t purport to find the "truth", whatever that may be. Scientific statements are, theoretically at least, always subject to a probability, no matter how small, of being in error, even when it is asserted to be correct. For example, it might be stated that rock A weighs 5.25 kilos. But a careful re-checking might show rock A to be 5.249 kilos. (In practice several measurements will yield a statistical mean.) A scientific statement will be held to be correct until further notice because it rests on a body of evidence that can be checked, but additional evidence in the future might mean the scientific statement or theory has to be modified or completely replaced to explain the new evidence. The most interesting theories will make predictions in the sense of directing scientists where to look for new evidence that would tend to validate or tend to invalidate the theory. Scientists still use the word "laws" of science largely because of tradition, but they are not absolute truths. You can overturn any of these laws if you can provide sufficient evidence from the real world that can be checked, or peer reviewed, by others. For example, the statement that the sun and not the earth is the centre of the solar system is a scientific statement (the heliocentric theory) that is considered valid because it explains a large body of evidence (facts from the real world). If you wish to try and overturn this theory you will need to present a new theory that adequately explains all the existing evidence whilst having the earth at rest. It isn’t hard to do. Everything could be a dream, for example, or, God made the universe ten minutes ago with all our memories, fossils, light from distant stars etc. completely intact with only the appearance of the sun at rest relative to the earth. But none of this is science. It isn’t testable but rather it is just assertion. Such assertions belong on the mountain of belief. The heliocentric theory is a scientific theory because it can be tested. In this way the heliocentric theory is considered valid until further notice, always with the possibility that in theory it could be overturned, but don’t hold your breath if you think it will be overturned anytime soon! (Ok, you can say they move relative to each other, but you know what I mean!) In the real everyday world people, scientists included, are likely to just say it’s true that the sun is the centre of the solar system, rather that constantly repeating "until further notice".
Therefore, unlike the belief fields, science has a method which can be checked or peer reviewed by others, checks and balances as it were, by which knowledge is secured that deliberately tries to minimize the many possibilities of human or mechanical errors, deliberate or otherwise. So when anyone says to you science cannot be trusted because some science has proved to be incorrect or even a fraud, you know they do not understand that it is the scientific method itself that has exposed such errors or frauds. In this way the scientific method is forever self-examining, self-checking. Any theory, especially at the frontiers of knowledge may prove to be inadequate or completely wrong and may need to be modified or replaced by another theory that explains facts or observations that the earlier theory could not. But the uncertainty at the frontier of knowledge does not invalidate the extremely well trodden foreground.
In this way science, or at least the empirical sciences, do not deal in absolutes. A scientific statement should not be considered as "absolute truth". That withstanding, common sense dictates that in everyday life we behave - quite rightly - as though some scientific "laws" were indeed absolutely true. You wouldn’t step off a twenty storey building on the supposition that at that exact moment the "law" of gravity would change. Would you?
Scientific statements, unlike statements of belief, are, in practice, falsifiable. However, a piece of evidence that contradicts a well established theory might not automatically overthrow it, but rather reveal how the theory can be modified to better explain that part of the real world it seeks to explain. But if the theory cannot be modified, it will have been falsified and a new better theory will be sought. In this way science is falsifiable whilst at the same time avoiding premature or naïve falsification. For example, should Newton’s theory of gravity have been automatically thrown out because it failed to explain the movements of Uranus, despite its excellent record in predicting the movements of the other planets? Obviously not. That would have been naïve falsification. As it turned out another theory was postulated that another as yet unknown planet was affecting the orbit of Uranus, and, using the very Newtonian celestial mechanics that were in question, it was calculated, or predicted, where that planet should be. Astronomers turned their telescopes to that part of the sky and Neptune was discovered. Despite Einstein’s refinements to gravitation theory, Newton is still sufficiently accurate to be used by rocket scientists to navigate the solar system.
At the cutting edge of science there may well be multiple hypothesis or theories all of which explain the currently known facts. As more facts come in, it is exciting to see which theory will prove to have been the most accurate! This is part of the excitement of science and this applies to evolutionary science. Science observes the fact that living things evolve by observing fast reproducing and mutating micro-organisms, and much more slowly evolving plants and animals which are so slow the process usually cannot be observed directly but can be observed over many lifetimes of the organism by looking at the fossil record. Information about the fossil record is constantly coming in and this will or will not fit some, all or none of the current theories as to how evolution took place. Was it a slow, gradual process as Darwin thought, or did change occur over a relatively short period of time followed by long periods without change (called Punctuated Equilibrium)? So when you hear people say that evolution is in trouble because evolutionist cannot agree with each other, or that a renowned evolutionist rejects Darwinism, or "Scientists reject Darwin!" you will know that they do not understand (or are dissembling) that the disagreements are between the competing theories as to how evolution takes place, and not about whether evolution took place in the first place.
But this isn’t just about evolution. It is Science v Creationism. We will define Creationism for our discussion as that particular brand that attempts to explain the universe in terms of the Bible, particularly Genesis. They try to give themselves credibility by calling it Creation Science. But as you can see from the introduction above, the very name tells you it must be a pseudoscience because the theory that God created everything in a recent creation cannot be tested, cannot be falsified. And it doesn’t matter whether you believe God created the world is six literal days or days of seven thousand years. This belongs on the mountain of belief. If it tries to set up camp on the mountain of research, it needs to be kicked back out because, as we have said, its premise invokes a supernatural, non-empirical concept. Nevertheless, it has gained many converts who have been duped into believing that it rests upon a foundation of real science and who are subsequently unable to tell the difference between science and pseudoscience.
