Question: What is the form of creationism that believes that the Earth was created less than 10,000 years ago and followed by Andrew Snelling?

Context paragraphs:
Creationist museum: A creationist museum is a facility that hosts exhibits which use the established natural history museum format to present a young Earth creationist view that the Earth and life on Earth were created some 6,000 to 10,000 years ago in six days.  These facilities generally promote Biblically-literalist creationism and contest evolutionary science, which has led to heavy criticism from the scientific community.

Geological history of oxygen: Before photosynthesis evolved, Earth's atmosphere had no free oxygen (O).  Photosynthetic prokaryotic organisms that produced O as a waste product lived long before the first build-up of free oxygen in the atmosphere, perhaps as early as 3.5 billion years ago.  The oxygen they produced would have been rapidly removed from the atmosphere by weathering of reducing minerals, most notably iron.  This "mass rusting" led to the deposition of iron oxide on the ocean floor, forming banded iron formations.  Oxygen only began to persist in the atmosphere in small quantities about 50 million years before the start of the Great Oxygenation Event.  This mass oxygenation of the atmosphere resulted in rapid buildup of free oxygen.  At current rates of primary production, today's concentration of oxygen could be produced by photosynthetic organisms in 2,000 years.  In the absence of plants, the rate of oxygen production by photosynthesis was slower in the Precambrian, and the concentrations of O attained were less than 10% of today's and probably fluctuated greatly; oxygen may even have disappeared from the atmosphere again around 1.9 billion years ago.  These fluctuations in oxygen concentration had little direct effect on life, with mass extinctions not observed until the appearance of complex life around the start of the Cambrian period,   million years ago .  The presence of O2 provided life with new opportunities.  Aerobic metabolism is more efficient than anaerobic pathways, and the presence of oxygen undoubtedly created new possibilities for life to explore.  Since the start of the Cambrian period, atmospheric oxygen concentrations have fluctuated between 15% and 35% of atmospheric volume.  The maximum of 35% was reached towards the end of the Carboniferous period (about 300 million years ago), a peak which may have contributed to the large size of insects and amphibians at that time.  Whilst human activities, such as the burning of fossil fuels, affect relative carbon dioxide concentrations, their effect on the much larger concentration of oxygen is less significant.

Young Earth creationism: 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.

Prehistoric demography: Prehistoric demography is the study of the demography of human and hominid populations from the origin of hominids about 6,000,000 years ago through the origin of anatomically modern humans about 200,000 years ago, to the beginning of the agricultural revolution about 10,000 years ago.

Hoodoo Mountain: Hoodoo Mountain is a potentially active flat-topped stratovolcano in the Stikine Country of northwestern British Columbia, Canada, located 74 km northeast of Wrangell, Alaska on the north side of the lower Iskut River and 30 km east of its junction with the Stikine River.  It is situated in the Boundary Ranges of the Coast Mountains and has been in existence since the Late Pleistocene stage of the Pleistocene epoch, which began 130,000 years ago and ended 10,000 years ago.  The mountain gets its name from the needle-like lava spines or hoodoos that reach heights of 150 m , which give the volcano a strange appearance.  This appearance makes Hoodoo Mountain different from other neighbouring mountains in the Boundary Ranges.

Late Glacial: The Late Glacial climate warming (c. 13,000–10,000 years ago), or Tardiglacial ("Late Glacial"), is defined primarily by the beginning of the modern warm period, in which temperatures in the Northern Hemisphere rose substantially, causing a process of accelerated deglaciation following the Last Glacial Maximum (c. 25,000–13,000 years ago).  At this time, human populations, previously forced into refuge areas as a result of Last Glacial Maximum (LGM) climatic conditions, gradually begin to repopulate the Northern Hemisphere's Eurasian landmass and eventually populate North America via Beringia for the first time.  The Late Glacial Interstadial c.14,670 to c.12,890 BP represents the first "pronounced" warming since the end of the LGM.

History of Jiangxi: The history of Jiangxi stretches from Lower Paleolithic times to the present, as Jiangxi was already inhabited by humans one million years ago.  Until recently, the earliest known Jiangxi pottery was dated to around 11000 BC,; however, recent finds show that the absolutely earliest known pottery, from ca. 18,000 BC, comes from Jiangxi In this Chinese province the full Neolithic period began before 8000 BC, as represented by Xianrendong culture in discovering cultivated rice over 10,000 years ago.  This period is followed by the Bronze Age around 2000 BC, represented by Wucheng culture and Dayangzhou culture, and by the Iron Age prior to 500 BC.

List of mammals of Mexico: This is a list of the native wild mammal species recorded in Mexico.  As of September 2014, there were 536 mammalian species or subspecies listed.  Based on IUCN data, Mexico has 23% more noncetacean mammal species than the U.S. and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors.  Mexico's high mammal biodiversity is in part a reflection of the wide array of biomes present over its latitudinal, climatic and altitudinal ranges, from lowland tropical rainforest to temperate desert to montane forest to alpine tundra.  The general increase in terrestrial biodiversity moving towards the equator is another important factor in the comparison.  Mexico includes much of the Mesoamerican and Madrean pine-oak woodlands biodiversity hotspots. From a biogeographic standpoint, most of Mexico is linked to the rest of North America as part of the Nearctic ecozone.  However, the lowlands of southern Mexico are linked with Central America and South America as part of the Neotropic ecozone.  Extensive mixing of Nearctic and Neotropical mammal species commenced only three million years ago, when the formation of the Isthmus of Panama ended South America's long period of isolation and precipitated the Great American Interchange.  Twenty of Mexico's extant nonflying species (opossums, armadillos, anteaters, monkeys and caviomorph rodents) are of South American origin.  Most of the megafauna that formerly inhabited the region became extinct at the end of the Pleistocene about 10,000 years ago, shortly after the arrival of the first humans.  Increasing alteration and destruction of natural habitats by expanding human populations during the last several centuries is causing further attrition of the region's biodiversity, as exemplified by the 'hotspot' designations (by definition, such areas have lost over 70% of their primary vegetation).

Andrew A. Snelling: Andrew A. Snelling is a young-Earth creationist geologist who works for Answers in Genesis.

Chaotian (geology): In the geologic record the Chaotian eon or era is unofficially proposed to denote the time preceding the solidification of the Earth's crust and the formation of Earth's moon, it is the earliest era within the eon of Hadean.  It lasted 196 million years, at   million years ago to the beginning of the Zirconian era,   million years ago .  It is named after Chaos, the primeval void in Greek mythology.  The Chaotian sets in with the emergence of Earth at 4.6 billion years ago.  Its upper limit and thus the transition to the Zirconian era is defined by the occurrence of the first conservation capable mineral.  These are zircon, the oldest mineral in the Jack Hills of Narryer Gneiss Terrane in Western Australia (Yilgarn craton) found and were dated 4,404 ± 8 million years ago
