i love myths, i wonder what you guys think is the most plausible myth out ther,e iv picked a few of my favourites, you can decide.
1. Chupacabra
Chupacabra (also chupacabras /tʃupa'kabɾas/, from Spanish chupar: to suck, cabra: goat; goats sucker) is a cryptid said to inhabit parts of both of the Americas. It is associated particularly with Puerto Rico (where it was first reported), Mexico, and the United States, especially in the latter's Latin American communities. The name translates literally from the Spanish as "goat sucker." It comes from the creature's reported habit of attacking and drinking the blood of livestock, especially goats. Physical descriptions of the creature vary. Eyewitness sightings have been claimed as early as 1990 in Puerto Rico, and have since been reported as far north as Maine, and as far south as Chile. Though some argue that the chupacabras may be real creatures, mainstream scientists and experts generally contend that the chupacabra is a legendary creature, or a type of urban legend. It is supposedly a heavy creature, the size of a small bear, with a row of spines reaching from the neck to the base of the tail
2. The Loch Ness Monster
The Loch Ness Monster is a cryptid, claimed to inhabit Scotland's Loch Ness, the most voluminous freshwater lake in Great Britain. The creature's "scientific" name, chosen by the late Sir Peter Scott in Nature, is Nessiteras rhombopteryx (Greek for "the wonder of Ness with the diamond shaped fin").[1] Anagram lovers soon followed this with the discovery that the letters could also say "Monster hoax by Sir Peter S".[2]
Along with Bigfoot and the Yeti, the Loch Ness Monster is one of the best-known mysteries of cryptozoology. Most scientists and other experts find current evidence supporting the creature's existence unpersuasive, and regard the occasional sightings as hoaxes or misidentification of known creatures or natural phenomena. Belief in the legend persists around the world, however. Local people, and later many around the world, have affectionately referred to the animal by the feminine name of Nessie.
3. Big Foot

Bigfoot, also known as Sasquatch, is a figure in North American folklore said to inhabit remote forests, mainly in the Pacific northwest region of the United States and the Canadian province of British Columbia. Bigfoot is sometimes described as a large, hairy bipedal hominoid, and many believe that this animal, or its close relatives, may be found around the world under different regional names, such as the Yeti of Tibet and Nepal and the Yowie of Australia.
Bigfoot is one of the more famous examples of cryptozoology, a subject that mainstream researchers tend to dismiss as pseudoscience because of unreliable eyewitness accounts and a lack of solid physical evidence. Most experts consider the Bigfoot legend to be a combination of folklore and hoaxes, but there are a number of authors and researchers who do believe that the stories could be true.
4. Area 51 Alien Life
Its secretive nature and undoubted connection to classified aircraft research, together with reports of unusual phenomena, have led Area 51 to become a focus of modern UFO and conspiracy theory. Some of the unconventional activities claimed to be underway at Area 51 include:
The storage, examination, and reverse engineering of crashed alien spacecraft (including material supposedly recovered at Roswell), the study of their occupants (living and dead), and the manufacture of aircraft based on alien technology.
Meetings or joint undertakings with extraterrestrials.
The development of exotic energy weapons (for SDI applications or otherwise) or means of weather control.
The development of time travel technology.
Activities related to a supposed shadowy one world government.
Many of the hypotheses concern underground facilities at Groom or at nearby Papoose Lake, and include claims of a transcontinental underground railroad system, a disappearing airstrip (nicknamed the "Cheshire Airstrip", after Lewis Carroll's Cheshire cat) which briefly appears when water is sprayed onto its camouflaged asphalt,[15] and engineering based on alien technology. In 1989, Bob Lazar claimed that he had worked at a facility at Papoose Lake (which he called S-4) on such a U.S. Government flying saucer.
A screenshot of Victor's alien interrogation video.One major hypothesis is that Area 51 is a place which simulates the environment of the moon. In 2000-2001, Fox Television broadcast a show about Apollo moon landing hoax accusations, in which it was suggested that the whole moon landing in 1969 was a hoax and was filmed in parts of Area 51.
Others, however, claim that during the mid 1990s, the most secret work previously done at Groom was quietly moved to other facilities, including Dugway Proving Ground in Utah, and that the continued secrecy around Groom is largely a successful attempt at misdirection.[16]
In July 1996, a man named "Victor" announced on Art Bell's Coast to Coast AM radio show that he had a videotape of an alien interrogation which had taken place in Area 51. He claimed that he had made a copy of the tape during a scheduled transfer of analogue videotape files on the base into digital form, and had then smuggled the copy out of Area 51. The video appears to show the head of an alien creature in a dark interrogation room, possibly using telepathy to communicate with military personnel and scientists.[17] The footage was eventually included in a video documentary entitled Area 51: The Alien Interview.
5. The Holy Grail
According to Christian mythology, the Holy Grail was the dish, plate, or cup used by Jesus at the Last Supper, said to possess miraculous powers. The connection of Joseph of Arimathea with the Grail legend dates from Robert de Boron's Joseph d'Arimathie (late 12th century) in which Joseph receives the Grail from an apparition of Jesus and sends it with his followers to Great Britain; building upon this theme, later writers recounted how Joseph used the Grail to catch Christ's blood while interring him and that in Britain he founded a line of guardians to keep it safe. The quest for the Holy Grail makes up an important segment of the Arthurian cycle, appearing first in works by Chrétien de Troyes.[1] The legend may combine Christian lore with a Celtic myth of a cauldron endowed with special powers.
The development of the Grail legend has been traced in detail by cultural historians: It is a legend which first came together in the form of written romances, deriving perhaps from some pre-Christian folklore hints, in the later 12th and early 13th centuries. The early Grail romances centered on Percival and were woven into the more general Arthurian fabric.
Some of the Grail legend is interwoven with legends of the Holy Chalice.
6. US Government involvement in 9/11
Since the September 11, 2001 attacks, a variety of conspiracy theories have emerged which dispute the mainstream account of those events. The theories typically include suggestions that individuals in (or associated with) the government of the United States knew of the impending attacks and refused to act on that knowledge, or that the attacks were a false flag operation carried out with the intention of stirring up the passions and buying the allegiance of the American people.
Some conspiracy theorists have claimed that the collapse of the World Trade Center was the result of a controlled demolition. Some also contend that a commercial airliner did not crash into the Pentagon, and that United Airlines Flight 93 was shot down.
Published reports by structural engineers do not support the controlled demolition hypothesis.[1] U.S. officials, mainstream journalists, and mainstream researchers have concluded that responsibility for the attacks and the resulting destruction rests solely with Al Qaeda.[2]
