1. The mighty Incan Empire of South America
The mighty Incan Empire of South America flourished between 1200 and 1535 AD. They developed drainage systems and canals to expand their crops, and built stone cities atop steep mountains such as Machu Picchu (above) without ever inventing the wheel. Despite their vast achievements, the Incan Empire with its 40,000 manned army was no match for 180 Spanish conquistadors armed with advanced weapons and smallpox.

2. Ancient Pyramids in Giza, Egypt

Khafre (l.) and Khufu (r.) are two of the three ancient Pyramids in Giza, Egypt. Khufu is the biggest, consisting of more than 2 million stones with some weighing 9 tons. The Pyramids, built as elaborate tombs for divine kings, date back to 2,550 BC. Modern Egyptologists believe that the Pyramids are made from stones dragged from quarries and, despite ancient Greek testimony, were built predominantly by skilled craftsmen rather than slave labor.

3. The Mayan Temple

According to the Mesoamerican Long Count Calendar, made famous by the ancient Mayan people, December 2012 marks the ending of the current baktun cycle. This little bit of information has many archeologists spooked. Some believe the Mayans were warning of a coming apocalypse, while others insist it’s simply a mathematical misconception.

4. The Legend of El Dorado

The Legend of El Dorado originates from the Muisca, who lived in the modern country of Colombia from 1000 to 1538 AD. In a ritual ceremony for their goddess, the tribal chief would cover himself in gold dust and jump into a lake as an offering. This spawned the legend of a lost golden city, which led Spanish conquistadors on a wild goose chase to nowhere.

5. Easter Island

Easter Island, also known as Rapa Nui, is remotely located 2,000 miles off the coast of Tahiti. The original settlers of the island were Polynesians who migrated to the far-off land between 400 and 600 BC. They built many shrines and statues, called moai, from stones quarried throughout the island including a volcano site. Researchers still question exactly how the large stones were moved.

6. The Bermuda Triangle

The Bermuda Triangle located in the Atlantic between Bermuda, Florida and Puerto Rico is a thief, stealing planes and boats right out of existence. The area got its name after Sgt. Howell Thompson (l.), along with 27 Navy airmen, vanished from the devilish spot during a routine flight in 1945. Rumors persist on a supernatural explanation, but many specialists blame hurricanes, a heavy Gulf Stream and human error.

7. The Nazca Lines

The Nazca Lines cover more than 190 square miles in the southern deserts of Peru. The mysterious shapes etched into the land rival football fields and predate the Incan Empire. The Las Manos figure (above) is 2,000 years old. Little is know about why the Nazca people constructed such vast pieces of sand art, some believe they are extraterrestrial in nature, while others claim they may have carried and pointed to sources of water.

8. Aliens

Area 51, located on Groom Lake in southern Nevada (c.), was founded in 1955 by the U.S. Air Force to develop and test new aircrafts such as the U-2 Spy Plane, A-12 Blackbird and F-117 Stealth Fighter. The secretive nature of the military base, combined with its classified aircraft research, helped conspiracy theorists imagine an installation filled with time-travel experimentation, UFO coverups and alien autopsies.

9. Sphinx of Giza, Egypt

Another Egyptian wonder, the Sphinx of Giza has the body of a lion and the head of a Pharaoh, believed by most to be that of king Khafre. It was carved from soft limestone, and has been slowly falling apart over the years. A popular theory of the missing nose claims Napoleon’s soldiers shot it off with a cannon in 1798, but early sketches discovered of the Sphinx without a nose predate Napoleon’s rampage.

10. The Loch Ness Monster

According to Scottish folklore, a mystical creature called a water horse lures small children to a watery grave by tricking them to ride on its sticky back. The Loch Ness Monster became an English wonder in 1933, after witness accounts made newspaper headlines. No hard evidence of the creature has ever been recorded with several pictures, including the one above, being proven as hoaxes.
