Sea cucumbers generally live on the sea bottom in areas close to the shore, and are grouped under the class Holothuroidea. The earliest known fossil specimens date back to the Devonian Period (417 to 354 million years ago). A comparison of sea cucumbers that lived 400 or 300 million years ago, and those living today shows that there is no difference between them. This lack of change demolishes the claim that living things evolved by developing gradually over very long periods of time. Contrary to what Darwinists maintain, living things did not come into existence as the result of any evolutionary process. Our Lord, God, Lord of the worlds, created all things, both living and inanimate.
