The perspective offered by hardcore creationists like Answers in Genesis forces people to choose between the Bible and modern science, and reinforces the harmful cultural stereotype that modern science and biblical Christianity cannot mix. Sadly, Answers in Genesis and their ilk are staking the authority of the entire Bible - and Christianity itself - on the view that a global flood is a viable alternative to abundant scientific evidence for a much longer chronology of creation. To do so, they must add in many speculative details not found in the biblical text, and they must rely on a theory of post-Flood animal evolution in which species diversify at rates many times faster than any known biological mechanism. These theories, along with many others posited by young-earth creationists, are not based on any credible scientific evidence, and in fact, they contradict the clear empirical evidence in God’s creation.
