Question: Young Earth creationism, believed by Andrew A. Snelling, holds that the universe, Earth, and all life on Earth were created by who?
Context: 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." David Russell Humphreys is a prominent American member of the young Earth creationist movement, with a PhD in physics.  He has proposed a theory for the origin of the universe which is supposed to resolve the distant starlight problem that exists in young Earth creationism. Answers in Genesis (AiG) is a fundamentalist Christian apologetics parachurch organization.  It advocates a literal or historical-grammatical interpretation of the Book of Genesis, with a particular focus on a pseudoscientific promotion of young Earth creationism, rejecting any results of scientific investigation which do not conform to their literal interpretation of the Genesis creation narrative.  The organization sees evolution as incompatible with scripture and believes anything other than the young earth view is a compromise on biblical inerrancy. Young Earth creationism (YEC) is a form of creationism, a religious belief which holds that the universe, Earth, and all life on Earth were created by direct acts of God less than 10,000 years ago.  Its primary adherents are Christians who subscribe to a literal interpretation of the creation narrative in the Bible's Book of Genesis and believe that God created the Earth in six 24-hour days.  In contrast to YEC, old Earth creationism is the belief in a metaphorical interpretation of the Book of Genesis and the scientifically-determined estimated ages of the Earth and Universe. Kevin R. Henke is an American geochemist and former instructor at the University of Kentucky's department of Geology.  He currently works as a senior research scientist at the University of Kentucky's Center for Applied Energy Research.  He is well known for his criticism of young earth creationism and the scientific arguments they make for a young earth.  In particular, he has been critical of the RATE project's results, which claim to show that zircons contain too much helium to be billions of years old, and has argued that Russell Humphreys, a young-earth creationist who was involved in the project, has made errors in his research.  These flaws include that, according to Henke, "The vast majority of Humphreys et al.'s critical a, b, and Q/Q0 values that are used in these "dating" equations are either missing, poorly defined, improperly measured or inaccurate."  Henke has also accused Humphreys of misidentifying his specimens, fudging his data, and not considering the possibility of helium contamination in this research.  He has also criticized John Woodmorappe for arguing that radiometric dating is unreliable.  On one occasion, Henke called Kent Hovind on the phone regarding Hovind's $250,000 challenge to "prove" evolution.  Hovind told Henke that in order to win the money he would have to recreate the Big Bang in a laboratory.  Henke responded by proposing several alternative "proofs" that pertained to geology (his field of expertise), but Hovind refused, saying that the project must be chosen by him and it must not pertain to the area in which Henke has scientific expertise.  Hovind therefore required Henke to prove that dogs and bananas had a common ancestor, and lowered the award to only $2,000 should he succeed.  Henke accepted the challenge, and later drafted a contract, which was then posted on Talk.origins.  However, one of Henke's requirements was that the judges be unbiased, and Hovind rejected the challenge for this reason, insisting that he should be the only one who can choose the judges. Gap creationism (also known as ruin-restoration creationism, restoration creationism, or "The Gap Theory") is a form of old Earth creationism that posits that the six-"yom" creation period, as described in the Book of Genesis, involved six literal 24-hour days (light being "day" and dark "night" as God specified), but that there was a gap of time between two distinct creations in the first and the second verses of Genesis, which the theory states explains many scientific observations, including the age of the Earth.  It differs from day-age creationism, which posits that the 'days' of creation were much longer periods (of thousands or millions of years), and from young Earth creationism, which although it agrees concerning the six literal 24-hour days of creation, does not posit any gap of time. Andrew A. Snelling is a young-Earth creationist geologist who works for Answers in Genesis. Progressive creationism (see for comparison intelligent design) is the religious belief that God created new forms of life gradually over a period of hundreds of millions of years.  As a form of Old Earth creationism, it accepts mainstream geological and cosmological estimates for the age of the Earth, some tenets of biology such as microevolution as well as archaeology to make its case.  In this view creation occurred in rapid bursts in which all "kinds" of plants and animals appear in stages lasting millions of years.  The bursts are followed by periods of stasis or equilibrium to accommodate new arrivals.  These bursts represent instances of God creating new types of organisms by divine intervention.  As viewed from the archaeological record, progressive creationism holds that "species do not gradually appear by the steady transformation of its ancestors; [but] appear all at once and "fully formed."  The view rejects macroevolution, claiming it is biologically untenable and not supported by the fossil record, and it rejects the concept of universal descent from a last universal common ancestor.  Thus the evidence for macroevolution is claimed to be false, but microevolution is accepted as a genetic parameter designed by the Creator into the fabric of genetics to allow for environmental adaptations and survival.  Generally, it is viewed by proponents as a middle ground between literal creationism and evolution. Old Earth creationism is an umbrella term for a number of types of creationism, including gap creationism, progressive creationism, and evolutionary creationism.  Old Earth creationism is typically more compatible with mainstream scientific thought on the issues of physics, chemistry, geology, and the age of the Earth, in contrast to young Earth creationism. The Ussher chronology is a 17th-century chronology of the history of the world formulated from a literal reading of the Old Testament by James Ussher, the Archbishop of Armagh (Church of Ireland).  The chronology is sometimes associated with young Earth creationism, which holds that the universe was created only a few millennia ago by God as they believe is described in the first two chapters of the biblical book of Genesis.
