Charles Darwin wasn't a particularly devout Christian, but I think his wife was more of a believer IIRC?
LadyOfTheManor - there really is a big difference between a scientific theory and a religious concept.
Scientific theory - looks at all the available evidence, suggests an explanation for it - looks for more evidence to see if it agrees or disagrees with the theory - refines the theory as required by the new facts, or throws it out completely. Theories also spawn new predictions - eg "if evolution did happen, we'd expect to find x and y" - can then look for those, or the opposite, or wait for things to be discovered which agree or disagree. The theory of evolution has been honed in that way for over 100 years, and is still the most convincing explanation of the available facts.
Religious concept - is happy to say "if the apparent facts don't fit, then your interpretation of the facts must be wrong" Does not lead to predictions which can be tested over time. Does not want to be refined by new facts.
Evolution cannot be "proven", but it can set itself up to be disproven and does so every day, and so far no-one is coming up with anything better in the way of scientific explanation.
Creation cannot be proven or disproven, because any criticism can be met with "You simply have to believe that God made it so"
