Structural and biochemical similarities prove common ancestry. The lack of fossil transitions strongly refutes this belief. Purposeful design can explain the same features in a more direct way. In addition, totally different organism often display similar features. The rock layers of the earth form the pages of earth's history showing millions of years of evolutionary progression.
Life is complex and well developed wherever it is found in the fossil record.
Major groups of plants and animals appear suddenly in the fossil record, with nothing leading up to them. Most rock layers and the fossils they contain can be explained better by a worldwide flood and subsequent events. They are accurate and reliable. Although radiometric dating methods seem to show a trend of great age, these methods depend upon numerous other assumptions. When used to date events of known age, such as lava flow in Hawaii or the Grand Canyon, they have been wrong by orders of magnitude.
