If the proponents of creationism uncovered some facet of the biological world that contradicted the theory of evolution, some scientists—though perhaps not all—would be intensely interested. Coming across an anomaly in science is like winning the lottery. Unexplained findings can offer a shortcut to scientific fame, as when Alexander Fleming noticed that mold was preventing the growth of staph bacteria in culture. But creationists have not come up with a single scientific observation that undercuts evolution. Biologists have demolished the few arguments that creationists have proposed, such as the idea of “irreducible complexity.” And at this point, creationist organizations such as the Discovery Institute in Seattle are spending most of their money on public relations rather than research.
“Why is evolution still a theory?” is a popular argument with the creationists I face. Trying to explain the difference is seen as twisting semantics to suit science’s “nefarious” goals.
