[Type of fallacy] Appeal to ignorance [Example] We refer the reader to the Answers in Genesis page on the non-constant speed of light.[4] It's interesting because the creationists who propose how the speed of light has changed have backed off from their claims, and now the website is claiming that a few scientific articles (like 2) make the possible claim for slight variations in the speed of light (much too small to explain the chronology problem), therefore it must have been different in the past, and therefore the whole speed of light is questionable and must be thrown out. Never mind the consequences if the speed of light changed from fast to slow; atoms and the energy of photons would be so messed up that the early creation earth would probably fry any young earth. Of course, the creationist just put a "time dilation field" around it, and everything is OK. Never mind that there is no evidence for it. [Definition] 
If something is not known to be false, it must be true.
