WHERE?The first crop circle, recorded in 1966, was discovered by an Australian sugar cane farmer who claimed to see a flying saucer spaceship rise up from a swamp before flying away.
WHAT'S THE STORY?Early crop circles were primitive circular patterns of flattened crops, often created in mysterious circumstances overnight, and attributed to aliens. They began at a time when flying saucers were hugely popular in sci-fi literature and movies. Over the decades, crop circles have evolved to be increasingly complex. Today, they appear in the form geometric shapes like the DNA double helix, or fractals like the nautilus shell.
WHERE?The first reported sighting of a UFO came from Texas in 1878, when a local farmer reported seeing a large, dark, circular flying object flying "at wonderful speed".
WHAT'S THE STORY?In the 1950s, the number of reported UFO sightings went through the roof. The most common kind were flying saucers, described to have awesome maneuvering capabilities beyond any man-made aircraft.
WHERE?For thousands of years, countless individuals from cultures around the world have reported what we now term as out of body experience. Because it feels so real, it's interpreted as a literal separation of a mind or soul from the physical body.
WHAT'S THE STORY?Such an event appears to be strong evidence for a spirit world, afterlife, and even alternate dimensions in which other intelligent beings exist. Could the OBE really prove the existence of life after death?
WHERE?The Pyramids of Giza in Egypt really are something special. We still don't really know how the Egyptians built the largest pyramid of all, known as the Great Pyramid of Cheops (or Khufu), some 5,000 years ago. Remember, this was even before the invention of the wheel.
The Pyramid of Cheops is the size of a 40-storey building and covers an area big enough to fit 10 football fields in it. More than 2 million stone blocks were used to make the pyramid, each weighing 2-5 tons and cut from a distant limestone quarry on the other side of the Nile. Experts reckon it took 400,000 men some 20 years to complete.
WHAT'S THE STORY?Engineering feats aside, these structures are claimed by some to possess the unexplained phenomenon of Pyramid Power. In the 1940s, a Czech radio engineer named Karel Drbal claimed that small pyramids of the same relative dimensions as the Great Pyramid (on a 1:1,000 scale) could sharpen razor blades. His explanation was that the pyramid shape focuses cosmic energy when precisely aligned on the north-south axis, which can renew the crystalline structure of steel.
5. The Unexplained Mystery of The Belmez Faces
WHERE?In 1971, in the small Spanish village of Belmez, Maria Pereira claimed a human face spontaneously appeared on her cement kitchen floor. It wasn't long before she destroyed the floor and replaced it - and a new face promptly appeared.
WHAT'S THE STORY?More and more faces continued to appear on the floor of Pereira's kitchen, attracting thousands of visitors every day. Some were male, some female, some large, and some small. In time, she discovered that the house, built around 1830, apparently stood above a graveyard used by the Romans, Spanish Muslims and then Medieval Christians.
Paranormal fans suggest that the faces were manifested on the floor by telekinesis. This notion was based on claim that the expressions on their faces used to change with the mood of Maria Pereira.
WHERE?According to some, theMayan prophecystates that the entire world as we know it will end on December 21, 2012.
WHAT'S THE STORY?The prophecy is based on the idea that when the ancient Mayans plotted our position in the Milky Way, they created an astrological calendar. They predicted that at the Winter Solstice in 2012, the Earth would pass into a new astrological phase. New Agers interpreted this as news that something dramatic would happen - namely, a global Apocalypse, or end of times, Biblical style.
WHERE?Stonehenge is a legendary neolithic monument made using stones transported to the Wiltshire countryside from Wales and built for unknown purpose.
WHAT'S THE STORY?Stonehenge is truly one of the great unexplained mysteries of the world. It's no hoax - estimated to be more than 5,000 years old - and is probably the most important prehistoric monument in the whole of Britain.
He's big. He's hairy. And he's starred in his own TV show.
WHERE?Bigfoot is famous for spooking the bejesus out of hikers and hunters in North America. Meanwhile, people living in the Himalayan regions of Nepal and Tibet talk of a giant humanoid creature know as the Yeti.
WHAT'S THE STORY?Bigfoot has been described as an intelligent ape-like creature living in the wild, some 6 to 10 feet tall and weighing more than 500 pounds. Witnesses claim he has large eyes, a heavy brow ridge and a crested head like a male gorilla. His alleged footprints are 24 inches long.
WHERE?The Loch Ness Monster is claimed to be a prehistoric creature that inhabits the Loch Ness in the Scottish Highlands. As lake monsters go, Scotland has tales of a fair few, with Nessie gaining the most popularity of all on the back of anecdotal evidence.
WHAT'S THE STORY?Nessie first hit the headlines in 1933 when a story was published in theInverness Courier. The report quoted a Londoner who had visited a few weeks earlier as seeing: "a most extraordinary form of animal... the nearest approach to a dragon or prehistoric animal that I have ever seen in my life."
After that, more sightings were reported and this unexplained phenomena hit international headlines. That same year, one motorcyclist claimed to nearly hit Nessie late one night as it lumbered across the road and slid back into the loch. Soon, apparent photos of the Loch Ness Monster were published.
Years later, digital enhancement of the footage revealed what seemed to be the rear body, flippers, and two more humps of a plesiosaur-like body. The technician said: "Before I saw the film, I thought the Loch Ness Monster was a load of rubbish. Having done the enhancement, I'm not so sure."
WHERE?The Bermuda Triangle is held responsible for the disappearance of countless airplanes and boats in the ocean between Florida, San Juan, and Bermuda. This area is one of the most heavily sailed shipping lanes in the world, with vessels crossing through daily for ports in the Americas, Europe and the Caribbean Islands.
WHAT'S THE STORY?Over the years, there have been a number of disappearances that happened in mysterious circumstances, which some people claim fall beyond the possibilities of human error, equipment failure or natural disasters. Paranormal fans talk of a suspension of the laws of physics.
The first unexplained event occurred in the 1950s when the story of Flight 19 came to light, detailing a group of five US Navy bombers on a training mission. The flight leader was reported to have said: "We are entering white water, nothing seems right. We don't know where we are, the water is green, no white." It was also claimed that Navy officials said the planes "flew off to Mars".
