Grand Canyon: A Different View: Grand Canyon: A Different View is a 2003 book edited by Tom Vail.  The book features a series of photographs of the Grand Canyon illustrating 20 essays by creationists Steve Austin, John Baumgardner, Duane Gish, Ken Ham, Russell Humphreys, Henry Morris, John D. Morris, Andrew A. Snelling, Larry Vardiman, John Whitcomb, and Kurt Wise.  It presents the Young Earth creationist perspective that the canyon is no more than a few thousand years old and was formed by the Global Flood or Noachian flood of the Bible.

Walt Brown (creationist): Walter T. Brown (Aug 1937) is a young earth creationist, who is the director of his own ministry called the Center for Scientific Creation. " The Skeptic's Dictionary" considers him to be one of the leaders of the creation science movement.  He proposes a specific version of flood geology called the Hydroplate Theory.  He is a retired army officer with a degree in mechanical engineering.

Biblical Creation Society: The Biblical Creation Society (BCS) is a United Kingdom-based creationary organisation founded in 1977 by Scottish minister Nigel M. de S. Cameron (now President of the Center for Policy on Emerging Technologies and a group of evangelical students, who were concerned about the popularity of theistic evolution among conservative Christians, but were repelled by the "wholly negative" attitude of the Evolution Protest Movement.  Although inspired by the scientific creationism of John C. Whitcomb and Henry M. Morris (authors of "The Genesis Flood"), it refused to limit its membership to only Young Earth creationists, and in its name rejected American attempts to separate scientific creationism from its Biblical roots (a separation rendered unnecessary by the lack of constitutional barriers to teaching creationism in the United Kingdom).  The organisation is based in Rugby, Warwickshire.

Noah's Ark: Noah's Ark (Hebrew: תיבת נח‎ ‎ ; Biblical Hebrew: "Tevat Noaḥ") is the vessel in the Genesis flood narrative (Genesis chapters 6–9) by which God spares Noah, his family, and a remnant of all the world's animals from a world-engulfing flood.  According to Genesis, God gave Noah instructions for building the ark.  Seven days before the deluge, God told Noah to enter the ark with his household and the animals.  The story goes on to describe the ark being afloat for 150 days and then coming to rest on the Mountains of Ararat and the subsequent receding of the waters.  The story is repeated, with variations, in the Quran, where the ark appears as "Safina Nūḥ" (Arabic: سفينة نوح‎ ‎ "Noah's boat").  The Genesis flood narrative is similar to numerous other flood myths from a variety of cultures.  The earliest known written flood myth is the Sumerian flood myth found in the "Epic of Ziusudra".

Henry M. Morris: Henry Madison Morris (October 6, 1918 – February 25, 2006) was an American young Earth creationist, Christian apologist, and engineer.  He was one of the founders of the Creation Research Society and the Institute for Creation Research.  He is considered by many to be "the father of modern creation science."  He is widely known for coauthoring "The Genesis Flood" with John C. Whitcomb in 1961.

Antediluvian: The Antediluvian (alternatively Pre-Diluvian or Pre-Flood, or even Tertiary) period (meaning "before the deluge") is the time period referred to in the Bible between the fall of humans and the Noachian Deluge (the Genesis Flood) in the biblical cosmology.  The narrative takes up chapters 1–6 (excluding the flood narrative) of the Book of Genesis.  The term found its way into early geology and lingered in science until the late Victorian era.  Colloquially, the term is used to refer to any ancient and murky period.

John C. Whitcomb: John Clement Whitcomb, Jr. (born June 22, 1924 in Washington, D.C.) is an American theologian and young earth creationist.  He is well known as the co-author with Henry M. Morris of "The Genesis Flood", which influenced many conservative American Christians to adopt Flood geology.

Flood geology: Flood geology (also creation geology or diluvial geology) is the attempt to interpret and reconcile geological features of the Earth in accordance with a literal belief in the global flood described in Genesis .  In the early-19th century, diluvial geologists hypothesized that specific surface features were evidence of a worldwide flood which had followed earlier geological eras; after further investigation they agreed that these features resulted from local floods or glaciers.  In the 20th century, young Earth creationists revived flood geology as an overarching concept in their opposition to evolution, assuming a recent six-day Creation and cataclysmic geological changes during the Biblical Deluge, and incorporating creationist explanations of the sequence of rock strata.

The Genesis Flood: The Genesis Flood: The Biblical Record and its Scientific Implications is a 1961 book by young earth creationists John C. Whitcomb and Henry M. Morris that, according to Ronald Numbers, elevated young earth creationism "to a position of fundamentalist orthodoxy."

Kent Hovind: Kent E. Hovind (born January 15, 1953) is an American Christian fundamentalist evangelist and tax protester.  He is a controversial figure in the Young Earth creationist movement and his ministry focuses on attempting to convince listeners to deny scientific theories in fields including biology (evolution), 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 has been criticized by Young Earth Creationist organizations like Answers in Genesis for his continued use of discredited arguments that have been abandoned by others in the movement.
