I think the major flaw of creationism is the lack of empirical data. Evolution, on the other hand, has numerous empirical data backing it up. For example, the law of gravity is a widely accepted law and almost no one would argue it otherwise. Why? Because of the obeservable data. I, along with other FSMers, can say that the FSM's invisible, intangible hand is pulling us all down. But that would be silly... it has no fact to support it. Creationism is the same way. I suggest you to read "The God Delusion" by Richard Dawkin(s?) if you are interested in my arguement: a word of warning though, if you are a die hard Christian, you WILL be offended by the book.
