At a glance, evolution and creationism are at drastic odds. One says that humans are descended from single-celled ocean creatures. The other that God created humans in approximately their current form.
Today, some argue that evolution and creationism are compatible. How can this be?
The way to argue for compatabilism is to assert that a definition of creationism, different from the common sense one, is in fact the correct one. So how are we to judge which definition is right? Let us examine the two candidate meanings of creationism.
The incompatabilist definition of creationism is that God created the world in 6 days less than 10,000 years ago, and created the animals approximately as they are today.
The compatabilist definition of creationism states: God created the world.
It may seem strange to choose between definitions when they mean different things, instead of simply assigning them different words. But ponder this question: which version of creationism should the proponents be defending, if they believe their theory is true and want to understand something through it?
There are two main things to be understood through creationism: Christianity, and physics. Thus, I propose that a bolder and scientific definition with more explanatory power would be better, and also one that matches the Bible.
Lots of explanatory power is preferable because explanations help us to understand. The incompatabilist definition says a number of things about reality, such as the age of the earth. In contrast, the compatabilist definition of creationism tells us very little; it doesn't give any details about God creating the world.
A more scientific definition is better for learning about physics because physics is concerned with scientific questions. To be scientific, a statement must be able to be criticised by observations or measurements.
Boldness is how much a statement exposes itself to criticism. Boldness is good because less bold statements are less conducive to making progress. This is because if one holds a bold theory, but is wrong, one stands the best chance of finding out his mistake and correcting it. By being exposed to criticism, bold, false ideas are best able to be replaced by better ideas.
The incompatabilist definition of creationism is partially scientific and very bold -- it would be proven false if we could show any of the following: the world is older than 10,000 years, the world was created in more or less than 6 days, or animals have changed significantly over the years. In contrast, the compatabilist definition of creationism is unscientific because no measurement or observation could possibly prove God didn't create the world. It is also less bold, because it uses vagueness to avoid being contradicted or criticised.
For creationism to help us understand Christianity, creationism must match what the Bible says about creation.
The incompatabilist definition of creationism matches the Bible very well. Someone unaware of the debate who was asked to write a book report summarising what the Bible says about creation would almost certainly say something similar. By contrast, the compatabilist definition was intentionally designed with concerns other than the scripture in mind, namely how to say something similar to the Bible without contradicting evolution. Thus it matches the Bible less well.
The incompatabilist definition has come out better on every count, and thus we shall use it.
On the incompatabilist side are arguments such as:
1) Without God, why would people act morally?
2) God created the world in 6 days, not billions of years.
3) Evolution says I came from a monkey; I didn't.
On the compatabilist side are arguments like:
4) Why can't I believe in evolution and creation?
5) Maybe God created the Big Bang then let evolution be his method of creating the world.
6) How do you know how long a day is before the sun is created? Maybe the six days God created the world in were billions of years long.
The first incompatabilist argument is a version of this argument: "If I am wrong, the world is grey and gloomy, therefore I am right." This is a fallacy because something depressing could be true.
The second argument is a claim about what creationism says. It matches our preferred definition, so it is strong for the same reasons we chose that definition.
The third argument contains a fallacy and a valid point. The valid point is that creationism says people did not come from lesser creatures, but evolution does, therefore they are in conflict. The fallacy is the implication that you should believe you didn't come from a monkey because this guy says you didn't, which is an argument from authority.
Moving on the the incompatabilist arguments, the fourth argument is ambiguous. It may mean that the arguer sees no contradiction between evolution and creation, thus they do not contradict (a fallacy -- argument from ignorance). Or it may mean that the arguer is not yet persuaded, which is no argument that he is right.
Argument five may seem reasonable, but it conflicts with our definition of creationism. It is poor for the same reasons the compatabilist definition of creationism is poor.
Argument six attacks the meaning of a day. This is very silly, because everyone, compatabilists included, live their lives as if a day is 24 hours long. For example, compatabilists show up for work on time, and do not say on Monday morning, "It's still sunday, I don't work today."
I conclude the incompatabilist position is better. Its definition of creationism is preferable, it has a strong argument behind it (that 6 days and billions of years are, in fact, different lengths of times), and no reasonable arguments for the opposing view exist.

Boldness is how much a statement exposes itself to criticism.
Scientific Proposition: A proposition that can be criticised by observations or measurements.
Explanatory Power is how much something tells us (about anything).
