1. Loch Ness Monster
The Loch Ness Monster, known as Nessie, lives in the black waters of the, 700-foot-deep, Loch (Lake) Ness in Scotland. The Loch Ness Monster remains one of the world’s most famous mysteries. Nessie is thought to be a giant creature with a huge rounded body, maybe 100 feet long, and a long neck. Some think it is a prehistoric seagoing dinosaur, pleiosaur.2. Bigfoot
Bigfoot is usually tall and hairy and ape like. People have reported sightings for hundreds of years. But, in 1967 two men caught a female Bigfoot on video. Then more and more people started doing the same.
3. Crop Circles
In the 1960s, the earliest crop circles were primitive circular patterns of flattened crops, often created in mysterious circumstances overnight. During the last 20 years, though, crop circles have evolved to be far more complex. They now form geometric shapes like the DNA double helix, or fractals like the nautilus shell. Whoever creates these mysterious patterns has become rapidly more advanced in just a period of a few decades. A bit like man.4. UFOs
The first reported UFO sighting happened in Texas in 1878, when a local farmer reported seeing a large, dark, circular flying object flying "at wonderful speed".
Another early sighting occurred in the UK in 1916, when a pilot reported seeing a row of lights that rose and disappeared into the sky.
5. The Pyramid Power
As unexplained mysteries go, 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-story 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.
