"Iona works hard to say why she doesn't like any of the scientific evidence but says nothing in support of YEC. If YEC is true, what evidence would you present to a non-believer, Iona? Or is it only possible to believe in YEC if you also believe in the bible? "

There is tons of evidence for creationism. I've posted a lot already! The Mosinee Jellyfish, man besides dinosaurs, the problem of causality and inductive inference, the problem of evil, the rate of fossilization, great Creation scientists of the past, Niagara falls and uniformity......Both evolutionists and Creationists see the very same evidence, but come out with two completely different interpretations. And only one can be right. I believe that my worldview best fits the facts of the worldwide picture; which strongly upholds Noah's Flood!
