Scientists theorize that the massive stone monument—which is in Wiltshire, England— was originally constructed around 2500 B.C. Some feel that Stonehenge was created by Merlin the magician; others assert it was a place of healing, and still others insist it’s a map for extraterrestrials. In 2007, archeologists found a similar structure at the bottom of Lake Michigan, prompting scientists to wonder if there is a connection between the sites.
Easter Island (also known as Rapa Nui), a small, isolated, volcanic island in the Pacific Ocean, is home to the famed Moai statues. Formed from volcanic rock, each of the humanoid statues is about 13 feet high and weighs approximately 28,000 lbs. Almost 900 of the sculptures exist, and although they were largely created between 1000 A.D. and 1650 A. D., there is no record of their meaning or purpose.
The Nazca Desert
Peru’s Nazca Desert features numerous, enormous geoglyphs that are so big, they can actually be seen from satellites. These line drawings represent a number of different shapes, including basic geometric forms, animals, and even some humanoid images. Since the pictures were created thousands of years ago–long before any conventional methods of flight were available—it’s thought they might be unofficial alien guidelines.
Nevada’s Highway 375
Also known as “The Extraterrestrial Highway,” this stretch of land boasts some of the most frequent alien activity in the world. Its 98 miles of lonely, open road run right near Area 51, the top-secret military base with rumored connections to alien life forms. It’s unknown whether UFOs are drawn to the base or simply enjoy the dark, desolate stretch of 375; either way, the number of reported sightings is astronomical.
Barra do Garças
Central Brazil has had multiple close encounters, and 12 acres of Barra do Garças was once dedicated to becoming the premiere landing pad for UFOs. (Unfortunately, construction of the Interspace Aerodrome was shelved indefinitely.) Additionally, Varginha, a city to the southeast, has its own special alien mythology; reportedly, this is where the Brazilian military once detained an alien of its very own.
The Ruins of Loulan
In modern-day Xinjiang, China, the ruins of the ancient kingdom of Loulan still mystify scientists and explorers. From roughly 400 B.C. to 100 B.C., Loulan was a primary city along the Silk Road; somehow, the city all but disappeared, only to be rediscovered in 1899. Although coffins, mummies and artifacts have been recovered, there’s no explanation for the city’s demise.
The “Bermuda Triangle” (also called the “Devil’s Triangle”) is the expanse of Atlantic Ocean contained within Miami, Florida; San Juan, Puerto Rico; and the Bermuda Islands. Many airplanes and ships that ventured into the Triangle crashed, sank, or completely disappeared. The area’s known for bizarre weather shifts and electromagnetic activity, and investigations have failed to unearth remains or confirm causes.
Machu Picchu, located in the cloud-grazing heights of the Andes Mountains, was once the toast of the Incan civilization. Researchers have ascribed many uses to the city, including spiritual training and astronomical observation. However, no one can accurately surmise why the city was completely abandoned in the early 1500s.
For some reason, Wisconsin attracts alien visitors like extraterrestrial moths to a flame. Sightings have included strange lights in both the sky and underwater, occasional crop circles and thousands of reported encounters. Paranormal researchers from around the world have studied the state’s long history of activity. Crop circles found within Wisconsin have been recorded as far back as the early 1940’s. Towns including Dundee, Elmwood and Bellville have really taken up the UFO mantle; since they’ve had so many sightings, Elmwood even hosts the annual UFO Days festival in July.
The Egyptian Pyramids
The Egyptian pyramids are still a marvel of physics, architecture and brute strength. Built between 3000 B.C. and 2500 B.C., the pyramids—which were tombs for Egyptian pharaohs—were supposedly created by more than 20,000 workers. But how did these laborers create such exacting angles? How did they build such enormous stone structures? And how did they manage to match the edges of certain pyramids to the cardinal directions? Perhaps alien intervention is the answer.
