Creationists are frequently accused of being anti-science...
Because some of them think the universe and the earth are 6000 years old. One must toss out a lot of science, and all that that science implies and infers, to take such a ridiculously irrational position.
No you don't. You just have to assume that the Creator interfered at some point, in a way that doesn't fit the current laws of nature, and didn't go out of His way to tell us about it.
There are other explanations, but that is one of the quickest ways there.
