7 Ancient Sites Some People Believe Were Built by ALIENS

0:00There are several places on Earth, awesome and mysterious, that evoke so many questions that some people believe they were built by or with the help of extraterrestrial intelligence. Let's explore those mystical destinations. In the hills above Kusuko Paru, you'll find an ancient Inka fortress called Saksehuaman, some of the massive stones of its walls weigh as much as 360 tons. They're cut and fitted together surprisingly precisely, and no mortar is used. The stones used for this construction were transported over 20 miles from quarries. But how did the Inka do it? Did they ask for extraterrestrial help? Perhaps. But archaeologists disagree. They have found evidence that the Inka used advanced engineering techniques involving ropes and levers to move and fit the stones. Okay, let's move on. To the Nazca lines. You can see them in the deserts of southern Paru. In this area, more than 800 lines and 300 shapes stretch across the deserted landscape. Those are called geoglyphs and are

And this is a pretty simple technique. You don't even need to use modern tools. The purpose of the Nazca lines is still a mystery, but most experts believe that they had some ceremonial significance. Now, the stone circle of Stonehenge must have something to do with extraterrestrial visitors, right? Those stones, some weighing as much as 50 tons, were brought from quarries hundreds of miles away. No wonder many people offered theories about alien intervention. Well, sorry to disappoint you, but archaeologists have proven that the monument could have actually been built with the help of technologies available around 5,000 years ago, such as wooden sleds and rollers. The exact purpose of Stonehenge is still under debate. Its builders could have used the stone circle to track the sun or to perform astronomy-related rituals. The next breath-stopping place on our list is the Egyptian pyramids, namely the pyramids of Giza just outside Cairo.

2:03They were built over 4,500 years ago. The largest of them, the great pyramid, is made of millions of two-toned stones which are arranged with super precision. The pyramids also align with the stars of Orion's belt, and this makes some people believe that aliens might have helped to build these awe-inspiring constructions. Experts disagree. They say that although the exact methods the Egyptian builders used are still unclear, the pyramids are undoubtedly a human achievement. Ramps, levers, and a large workforce were likely used to move the stones into place. Then, how about Teotihuacan, located near modern-day Mexico City? Once, it was a thriving metropolis. The city was built more than 2,000 years ago, and its size and advanced architecture make people wonder if aliens play a key role in its construction. In reality, the city was created by several cultures, including the Maya and Zapotec. It was a center for trade, agriculture, and other activities, but it does have some connection to

Now, let's travel to one of the most mysterious islands in the world, Easter Island, nearly 900 stone figures known as Moai stand there. Some towering over 30 feet tall. These statues were carved from volcanic rock more than 1,000 years ago, and moved across the island to their final resting places. This impressive feat, as well as the slightly creepy appearance of the figures, makes you think about some alien intervention, doesn't it? Well, another disappointment. It's believed that the Rapa Newi people used wooden sleds or rolling logs to transport the statues, and there's no evidence that extra terrestrials were involved. The last destination isn't even on Earth. In 1976, NASA's Viking 1 Orbiter captured an image of what seemed to be a face on Mars. It sparked numerous theories about alien activity. The face seems to be staring up from the

4:07Martian surface, like evidence of the activity of an ancient alien civilization. But more detailed images from 2001, taken by the Mars Global Surveyor, revealed that the so-called face was just a natural mesa, an isolated flat-topped hill with steep sides.
