Kent E. Hovind is an American Christian fundamentalist evangelist and tax protester. He is a controversial figure in the young Earth creationist movement whose ministry focuses on denial of scientific theories in the fields of biology, geophysics, and cosmology in favor of a literalist interpretation of the Genesis creation narrative found in the Bible. Hovind's views, which combine elements of creation science and conspiracy theory, are dismissed by the scientific community as fringe theory and pseudo-scholarship. He is also controversial within the Young Earth Creationist movement; Answers in Genesis openly criticized him for continued use of discredited arguments abandoned by others in the movement.
