The major disputes Creationists have with the theory of evolution relate to:
1. The age of the Earth. Fossils, carbon dating and other estimates of the Earth's age dispute the Creationist idea that the Earth is only a few thousand years old.
2. The theory of natural selection and evolution. Creationists believe that all live is designed, and point to complicated structures such as the eye as proof of design. The theory of evolution and natural selection provides an hypothesis for such structures to occur through evolution, starting from more simple designs, and becoming more complex.
