Science works by applying a set of agreed fundamental requirement, based on the principles of logic, mathematics, and established accepted scientific axioms, to all hypotheses. All competing hypotheses must meet these basic requirements and each will stand or fall according to how well or badly the presented supporting evidence, when view according to these principles, supports the hypothesis. No serious scientist would expect to get away with pleading that his favourite hypotheses should be exempt from, say, an accepted fundamental law and least of all from one which is fundamental to his hypothesis.
For example, imagine a scientist who is proposing a new hypothesis explaining flight and claiming it is a much better account of how an aircraft flies than any other. In fact, it is so brilliant that it utterly destroys the science of aerodynamics and will require the fundamental laws of physics to be re-written.
He has rightly pointed out that a fundamental requirement of any aerodynamic theory is that it must explain how an object in flight in air is apparently defying gravity and is able to move up and down in a controlled manner in a gravity field. However, it has been pointed out to him that, applying HIS hypothesis would not actually explain anything. If it were true, no object would actually be able to leave the ground, let alone move up or down in the air, in a controlled manner or not.
Imagine the reaction from his fellow scientists when he retorted that this was not a problem for his hypothesis because it was a special case and was exempt from any principle or principles which rendered it false. How long do you think this scientist’s credibility would last? About as long as it took his fellow scientists to stop laughing and persuade their incredulous colleagues that he had really made that claim - and was not even joking!
Now, consider the Creationist hypothesis concerning causality. They will argue that all things must have a cause (ignoring things like spontaneous decay of radioactive isotopes, which don’t, but let’s ignore that with them for the time being). The argument goes that, since everything must have a cause, there must have been a prime cause for all things and that the only possible prime cause must have been their favourite god. They also argue that this is an absolute universal law of logic from which nothing can escape and to which all scientific theories must be subject, with absolutely no exceptions.
We can also ignore the fact that, even if this was true, it would not establish that this prime causing is their favourite god, or anything even remotely like it. Assume for a moment that creationists have established somehow that the need for a prime cause IS an absolute and immutable fundamental law of the universe and that any such prime cause can only be their god.
“Ah!” You’ll no doubt now be saying, “What was the cause of the creationist god?” And you’d be entirely correct. Applying our universal immutable law to which all things must be subject, the creationist god must also have had a cause. The ‘prime cause’ is not prime at all.
Okay, so let’s hypothesise a cause before the prime cause (a sub-prime cause?). In fact, we now have to hypothesis an infinitely regressing continuum of pre-pre-pre- (ad infinitum) prime causes. In fact our prime cause hypothesis does not explain causality at all. The prime cause hypothesis has just collapsed under its own absurd logic. It has spectacularly falsified itself, something only possible for the more absurd hypotheses.
“No!” Creationists will retort. “My hypothesis is a special case and is exempt from its own fundamental law! Everything else is obliged to pass the test of my first cause hypothesis, but my god is exempt. It is a special case to which special laws apply. It is not fair to expect it to compete with science on an equal footing”. And they are not even joking. Special pleading is a fundamental part of almost all theology!
The creationist’s god is like a special needs child which can’t be expected to compete on an equal footing with normal children. It needs affirmative action and special provisions to be able to lead the semblance of a normal existence. These sentiments would be quite understandable, even laudable from the point of view of parents who have such an unfortunate child, but why have creationists created a god with so many handicaps and challenges that it needs to be treated as a special needs child?
The answer of course, is that they had no choice. Their problem is that their god IS handicapped. These handicaps were inherited from its parents. It was created by people who find reality difficult to understand and so constantly strive to live in an alternate one: one with simplistic answers, carefully constructed so as to be amenable to people with little or no learning and who take comfort in ignorance.
So of course it too can’t cope with reality either. Imaginary friends are only as good as the minds that imagine them.
