Pseudoarchaeology—also known as alternative archaeology, fringe archaeology, fantastic archaeology, cult archaeology, and spooky archaeology—is the interpretation of the past by people who are not professional archaeologists and who reject or ignore the accepted data gathering and analytical methods of the discipline. These pseudoscientific interpretations involve the use of artifacts, sites or materials to construct scientifically insubstantial theories to strengthen the pseudoarchaeologists' claims. Methods include exaggeration of evidence, dramatic or romanticized conclusions, use of fallacious arguments, and fabrication of evidence.
Ancient astronauts refer to a pseudoscientific set of beliefs which holds that intelligent extraterrestrial beings visited Earth and made contact with humans in antiquity and prehistoric times. Proponents suggest that this contact influenced the development of modern cultures, technologies, religions, and human biology. A common position is that deities from most, if not all, religions are extraterrestrial in origin, and that advanced technologies brought to Earth by ancient astronauts were interpreted as evidence of divine status by early humans.
Graham Bruce Hancock is a British writer who promotes pseudoscientific theories involving ancient civilizations and hypothetical lost lands. Hancock speculates that an advanced ice age civilization was destroyed in a cataclysm, but that its survivors passed on their knowledge to hunter-gatherers, giving rise to the earliest known civilizations of ancient Egypt, Mesopotamia, and Mesoamerica.
A flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primaeval waters which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life".
Clovis culture is a prehistoric Paleoamerican archaeological culture, named for distinct stone and bone tools found in close association with Pleistocene fauna, particularly two Columbian mammoths, at Blackwater Locality No. 1 near Clovis, New Mexico, in 1936 and 1937, though Paleoindian artifacts had been found at the site since the 1920s. It existed from roughly 11,500 to 10,800 BCE near the end of the Last Glacial Period.
Usselo ['ʏsəloː] is a Dutch village in the municipality of Enschede in the eastern Netherlands region of Twente. It is located just west of Enschede and east of Boekelo. It has existed for over 800 years. Archaeology shows that the region was inhabited more or less continuously since the last ice-age. The region is very fertile and will support agriculture and cattle. The countryside is marked by artificial hills, called es or esch, which were formed by depositing dung mixed with dirt. A prime example is the Fleringer Esch, near Fleringen.
Fingerprints of the Gods: The Evidence of Earth's Lost Civilization is a 1995 pseudoarcheology book by British writer Graham Hancock, which contends that an advanced civilization existed in prehistory, one which served as the common progenitor civilization to all subsequent known ancient historical ones. The author proposes that sometime around the end of the last ice age this civilization ended in cataclysm, but passed on to its inheritors profound knowledge of such things as astronomy, architecture and mathematics.
Michael G. L. Baillie is Professor Emeritus of Palaeoecology at Queen's University of Belfast, in Northern Ireland. Baillie is a leading expert in dendrochronology, or dating by means of tree-rings. In the 1980s, he was instrumental in building a year-by-year chronology of tree-ring growth reaching 7,400 years into the past.
The Hall of Records is a purported ancient library that is claimed to exist underground near the Great Sphinx of Giza in Egypt. The concept originated with claims made by Edgar Cayce, an American who claimed to be clairvoyant. He said in the 1930s that the civilization of Atlantis was destroyed around 10,500 BC and that Atlantean refugees built the Hall of Records at Giza to preserve their knowledge. Cayce's assertions had many precursors, particularly the pseudoscientific theories about Atlantis that Ignatius Donnelly promulgated in the late 19th century and claims about hidden chambers under the Sphinx that were made by H. C. Randall-Stevens and Harvey Spencer Lewis in the years before Cayce described the Hall of Records.
William M. (Bill) Napier is the author of five high tech thriller novels and a number of nonfiction science books.
Mark Boslough is an American physicist at Los Alamos National Laboratory, research professor at University of New Mexico, fellow of the Committee for Skeptical Inquiry, and chair of the Asteroid Day Expert Panel. He is an expert in the study of planetary impacts and global catastrophes. Due to his work in this field, Asteroid 73520 Boslough was named in his honor.
The Younger Dryas impact hypothesis (YDIH) or Clovis comet hypothesis is a speculative attempt to explain the onset of the Younger Dryas (YD) cooling at the end of the Last Glacial Period, around 12,900 years ago. The hypothesis is controversial and not widely accepted by relevant experts.
Andrew Michael Tangye Moore, also known as A. M. T. Moore, is a British archaeologist and academic. He is a professor at the Rochester Institute of Technology (RIT).
Steven M. Stanley is an American paleontologist and evolutionary biologist at the University of Hawaii at Manoa. He is best known for his empirical research documenting the evolutionary process of punctuated equilibrium in the fossil record.
The Corossol structure, which is also known as the Corossol crater, is a circular, 4.3-by-3.9-kilometre in diameter, underwater bedrock feature that is exposed on the gulf floor of the northwestern Gulf of Saint Lawrence 20-kilometre (12 mi) offshore of the city of Sept-Îles, Quebec, in eastern Canada. It is hypothesized to be a possible pre-Pleistocene, extraterrestrial impact structure. It lies underwater at a depth of 40–208-metre (131–682 ft). This underwater feature was found during the study of high-resolution bathymetric and sub-bottom profiler data collected south of the city of Sept-Iles in the northwestern Gulf of Saint Lawrence.
James Lawrence Powell is an American geologist, writer, former college president and museum director. He chaired the geology department at Oberlin College later serving as its provost and president. Powell also served as president of Franklin & Marshall College as well as Reed College. Following his positions in higher education, Powell presided over the Franklin Institute and the Natural History Museum of Los Angeles.
Pilauco is a paleontological and archaeological site located in the city of Osorno in Southern Chile. The site contains both human made lithic artifacts and megafauna remains–including gomphotheres. All the horizons containing megafauna and evidence of human activity date to the late Pleistocene. The calibrated radiocarbon dates indicate there was human activity in the site between 16,400 and -12,800 cal years B.P.
Although diamonds on Earth are rare, extraterrestrial diamonds are very common. Diamonds small enough that they contain only about 2000 carbon atoms are abundant in meteorites and some of them formed in stars before the Solar System existed. High pressure experiments suggest large amounts of diamonds are formed from methane on the ice giant planets Uranus and Neptune, while some planets in other planetary systems may be almost pure diamond. Diamonds are also found in stars and may have been the first mineral ever to have formed.
Ancient Apocalypse is a 2022 Netflix documentary series, where the British writer Graham Hancock presents his pseudoarchaeological theories about the alleged existence of an advanced civilization active during the last ice age.
