This whole creationism vs evolution thing is silly. It is mostly a false argument sent to get people all riled up instead of focussing on God. I take the Catholic stance on the matter, advocated by Pope Pius XII in his 1950 encyclical Humani Generis, with a few points:

• Scripture does not contradict evolution. Read.
• Scripture is very nuanced and should not all be interpreted literally. Read.
• Evolution is a very broad list of topics, be specific. Read.
• Evolutionary theory has the scientific upper hand. Always check the claims of creationists at Talk origins.
