If mainstream science willingly and in an unbiased fashion carefully tested the claims of creationists there would be no reason for all these websites, just a communal commitment to scientific truths.
Where are the creationist experiments to test their own claims? If they reject radiocarbon dating's correlation with varve dating, tree-ring dating, etc., where is their own research to back up their conclusions?
Come out of the box. You don't "believe". You either know or do not know.
You believe you know. The more evidence you have, the more confidence you have that what you "know" matches reality. The less evidence you have, the more you have to rely on belief and the less (real) confidence you have in what you "know".
You pretend to be confident that you "know" but you don't present any evidence. Your belief is empty.
