Creationists deny evolution, but to do that they have to carefully avoid ever looking at the fossil record. If they looked, they would see gradual change in the fossils. Instead of purposeful design, they would see meandering development without foresight. They would see how everything comes about by modifying some previous organ, sometimes repurposing it. With a bit of study, they would see how the changes are always reacting to adapt to the current environment. You would see how fossils are laid out in thin layers, with the more advanced plants and animals on top. You would see a tree of life. You would see 90% of species going extinct.
You could learn how to date fossils with radiometric dating, tree rings, volcanic ash layers, proximity to other well-known fossils.
All you would see is in perfect agreement with the theory of evolution. On the other hand, nothing about what you would discover matches the creationist view.~ Roedy (1948-02-04 age:69)
