The fossil record proves evolution. There are no clear transitions between vastly different types of animals in either the living world or the fossil record. Any three objects can be lined up but this does not prove that one turned into the other. 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.
