It is this fact which requires explanation. Darwin sought to explain both the fossil and contemporary records through his hypothesis. Although Darwinian evolution is supported by considerable evidence, it is not the only hypothesis under consideration. Neither is it the only one testable through the rules of observation and experiment. As such, if it fails, creationism does not thereby become the only remaining alternative explanation.
Science is a process, a way of thinking.
Science deals with physical evidence to explain the world around us. Matters of science are not to be confused with matters of faith. Things which are not testable through observation and experimentation necessarily lie outside the realm of science. The Creator, they say, brought life and the earth and the entire universe into being 6000 years ago or so, complete with all the evidence for an eons-long evolutionary development. The fossil record, the decaying radioactivity, the receding galaxies were all created as they are, and the evidence they present is an illusion.
