Science and Myth

It seems to me that the disagreements between 'evolutionists' and 'creationists' are not really about science. They seem to be about the validity of various truth-finding methods. I have heard assertions from Es, that the only data that may be considered is physical data, science. But many Cs will assert that 'faith' is legitimate evidence for the validity of their position.Here's the question, can we obtain true data only from science? Or are there other methodologies to choose from?Evan
