While the Orion constellation is named after the hunter in Greek mythology, it is anything but stealthy. Orion, which is located on the celestial equator, is one of the most prominent and recognizable constellations in the sky and can be seen throughout the world. Orion is clearly visible in the night sky from November to February. Orion is in the southwestern sky if you are in the Northern Hemisphere or the northwestern sky if you are in the Southern Hemisphere.
As such, some suggest the ancient builders of the Egyptian pyramids, the Nasca lines, and others were following an extraterrestrial instruction manual. After all, humans are on the threshold of expanding our reach in space, and places like Mars are in our sight.
And invoking a supernatural explanation for some of the most monumental of human achievements means skipping over the fascinating ways in which prehistoric civilizations managed to make some of the largest and most enigmatic constructions on Earth. The 1,year-old interlocking fortress walls are made of rocks that weigh as much as tons each, and which were carried more than 20 miles before being lifted and fit into place with laser-like precision. How an ancient culture accomplished such a feat of engineering is a fun little problem to solve; turns out the Inca were as adept at building houses and fortified complexes as they were at watching the sky and keeping calendars.

More recently, archaeologists have uncovered traces of the rope-and-lever system the Inca used to transport stones from their quarries to their cities—a system that relied on strength and ingenuity, rather than alien architects. On a high and dry plateau some miles southeast of Lima, more than long, straight white lines are etched into the Peruvian desert, seemingly at random. ing them are geometric shapes and 70 figures of animals, including a spider, monkey, and hummingbird. The longest of the lines run straight as an arrow for miles.
The biggest shapes stretch nearly 1, feet across and are best viewed from the air. Scientists suspect the Nasca drawings are as many as two millennia old, and because of their age, size, visibility from above, and mysterious nature, the lines are often cited as one of the best examples of alien handiwork on Earth.
Otherwise, how would an ancient culture have been able to make such huge des in the desert without being able to fly? And why? Called geoglyphs, these enigmatic des are made by removing the top, rust-colored layer of rocks and exposing the brighter white sand underneath. The why is a bit tougher to comprehend. First studied in the early s, the des were initially suspected to be aligned with constellations or solstices, but more recent work suggests the Nasca lines point to ceremonial or ritual sites related to water and fertility.

And in addition to being visible from the air, the shapes can be seen from surrounding foothills. Built more than 4, years ago, the Pyramids at Giza are monumental tombs where ancient queens and pharaohs were buried. But how, exactly, did the Egyptians build these things? The Great Pyramid is made of millions of precisely hewn stones weighing at least two tons each. As well, alien theorists often point to the fact that these three pyramids are in way better shape than others built centuries later never mind the amount of work that has gone into preserving them over the past several centuries.
A huge circle of stones, some weighing as much as 50 tons, sits in the English countryside outside Salisbury. No one knows what, exactly, the meaning of Stonehenge is, but, as with all the other sites in this collection, the explanation is not aliens.

Scientists suspect that over centuries, a mix of cultures including Maya, Zapotec, and Mixtec built the city that could house more thanpeople. And how did the moai end up on Easter Island? The figures average 13 feet tall and weigh 14 tons and appear to have been chiseled from the soft volcanic tuff found in the Rano Raraku quarry. There, more than statues are still in various states of construction, with some completed figures awaiting transportation to their intended resting place.
The reasons for carving the moai are mysterious, though they were likely sculpted for religious or ritual reasons. Spotted by the Viking 1 orbiter inthe so-called face is nearly two miles long and is in a region called Cydonia, which separates the smooth plains of the Martian north from the more cratered terrain in the south. Turns out that what had appeared to be a face is just another boring old Martian mesa, kind of like the landforms that litter the U.
