I base this on the many hours I have spent at these sites. I did offer to take any random site and demonstrate this--it was a challenge. Joe declined to accept it, but nominated Answers in Genesis as what he thought was an informative and accurate website. And he's right, of creationist websites, it's the best of the lot. So I will show you inaccurate, unscientific and misleading information from AiG.
We start with their "Statement of Faith":
[FONT=Book Antiqua, Times New Roman, Times]"No apparent, perceived or claimed evidence in any field, including history and chronology, can be valid if it contradicts the Scriptural record." (from AIG-USA)
[FONT=Book Antiqua, Times New Roman, Times]So we see immediately that they have already determined their conclusions, and will disregard or throw out any evidence that, to them, appears to contradict scripture. In doing this, they have declared that they are not doing science, as fundamental to any scientific enterprise is the commitment to follow the evidence wherever it may lead, whether it affirms scripture or refutes it.
[FONT=Book Antiqua, Times New Roman, Times]It is easy to find examples of outright falsehoods at AiG. For example, YECs were quite discombulated by the fabulous discovery of Tiktaalik Rosae, a species intermediate between fish and amphibians, because they constantly assert that there never were any such creatures. Therefore they went to work to try to say that is isn't what it is. In their article, by a non-paleontologist, they said, [/FONT][/FONT][/FONT]This is simply false. There is no such thing as an Evolutionist. They people they are refuting are called paleontologists. No paleontologiest says that lobe-fin fish are extinct, because they're not. Had they found a paleontologist to write their article, they would have known this. They can't, because there are no creationist paleontologists. Anyone who spends his or her life studying fossils knows that the theory of evolution is the only logical explanation for them. Then, regarding the coelancth, the author says, "it didn't evolve; it didn't change; it looked like the one found in the fossil record." This is false. Modern coelancths have evolved tremendously from extinct, ancient species, as any paleontologist knows.
Then he spends a lot of time arguing that Tiktaalik could not have walked on land. Is he stupid, ignorant or dishonest? It's hard to tell. The people who discovered Tiktaalik never claimed that it could walk on land. This dishonest form of argumentation is called "straw man."
Well, I could go on and on ripping AiG apart, since none of its article are written by qualified scientists who know what they're talking about. AiG is basically the brainchid of Ken Ham. Ken Ham is not a science. He has a Bachelors in "Applied Science" and a Diploma (Australian equivalent to Master's) in Education. He has never done any scientific research in any field or published any scientific article in any scientific journal. Ever. In his life. Because he's not a scientist. The other honcho there is Monty White, a chemist. You will also find articles by Jonathan Sarfati, another Chemist, and Michael Oard, a metereologist. What is missing from this list? Biologists. And, of course, evolution is a biological theory. They're just happy to get anyone who works in science at all. It doesn't bother them that these guys are completely unqualified to write on the subjects they try to address. They're not doing science; they're doing public relations.[FONT=Book Antiqua, Times New Roman, Times]
[/FONT]No, and I'll tell you why. There is no such thing as a creationist scientist. There are thousands of scientists who are Christians. But doing science means following the evidence where it leads, not presuming the answer and then looking for evidence to confirm it. Creationism rejects the scientific method itself, then clothes itself in the appearance and (when it can) the fake credentials of science. By rejecting science while trying to persuade people they are doing science, they are inherently dishonest. I'm sure there are. The difference is that science has a mechanism for discovering falsehood and exposing it. Creationism does not, which is why you see the same old lies: dinosaur footprints next to human, polystyrate fossils, dinosaur soft tissue, head-first ichtysaurs, etc. etc.
