There’s a clumsy little two-step move creationists like to make: first, point to dissent in the scientific community over real and often interesting issues at the edge of knowledge, and second, swap in their dissent over basics, like common descent, and pretend that the scientists are actually sharing in their ignorance-based concern. John Timmer has a good summary of a few genuine scientific arguments, contrasted with the bogus arguments creationists pretend are important.
There are some good and interesting questions out there. The creationists, and I include the phonies at the Discovery Institute among them, never ask them.
One other point Timmer brings up at the end: should the real scientific controversies be part of the public high school curriculum? He thinks not, and I agree — I’d rather the high schools prepared students with a general understanding of the most basic principles, rather than rushing off to pursue details with which the students won’t yet be able to cope, anyway.
