You are a bit stubborn aren't you?
I gave you evidence from very reliable sources that your highly qualified scientists were wrong.
"The above quote is, to my knowledge, the first salvo by Australian creationist Barry Setterfield regarding his hypothesis of "c-decay," the notion of the decreasing speed of light that has been used for years as evidence for a young universe. Setterfield's hypothesis, while initially embraced by the majority of the creationist community, received heavy criticism from the scientific establishment for several years since its introduction in 1981, and was finally rejected by the creationists themselves after it became such a major embarrassment that even the San Diego-based Institute for Creation Research rejected it (Acts and Facts , May 1988, G. Aardsma)."
