Human history abounds with concepts and creations that appear too cutting-edge for their epoch. Buildings and constructions included. We’re referring to colossal rocks sculpted with unbelievable accuracy, structures oriented with the heavens, and monuments so enigmatic and scientifically noteworthy that they leave contemporary engineers, architects and astrophysicists scratching their heads raw. Researchers are constantly suggesting theories about how these marvels were crafted, yet they never quite ring true. Consequently, with the passage of time, certain individuals have looked to more unconventional interpretations. If (and we must stress the word ‘if’ here) – let’s say – extraterrestrials once dabbled in ancient design… Well, these ten could easily be their greatest hits… (Pictures: Getty Images/Metro)
The Kailasa Temple, India
This truly stunning Hindu temple, situated in Ellora, India, was carved from a singular, solid mass of volcanic stone during the 8th century. Laborers extracted approximately – prepare yourself – 200,000 tons of rock from the apex downwards, fashioning a detached edifice replete with statuary, pillars, and sacred sites. Its precision is so refined that it resembles a meticulous assembly by an exceedingly patient deity (Picture: Getty Images)

Nobody knows the duration of this remarkable temple’s construction. Nor the instruments employed by its creators. Yet, even with state-of-the-art equipment, it presents a considerable challenge. Legend suggests its creation occurred overnight through divine directive. Perhaps with a touch of assistance from some alien beings…? Unlikely, though we remain receptive, don’t we?

The Great Pyramid of Giza, Egypt
Constructed around 2560 BCE, the supremely iconic Great Pyramid of Giza once radiated with burnished white limestone and reigned as the tallest construction on Earth for almost 4,000 years. Each facade aligns almost impeccably with true north, and the exactitude of its 2.3 million blocks is truly astounding. Certain stones tip the scales at over 70 tons, yet the seams are tighter than contemporary brickwork (Picture: Getty Images)

Numerous individuals have tried, yet none can fully elucidate how Bronze Age builders managed to erect the pyramids so faultlessly using copper chisels and wooden skids. Hence the proliferation of conjecture that perhaps they were not alone. Perhaps someone imparted insights on load distribution and cosmic geometry before disappearing into the desert night aboard a silver vessel. Simply a notion (Picture: Getty Images)
Puma Punku, Bolivia
Integral to the ancient Tiwanaku complex, Puma Punku represents a formidable stone enigma. Massive blocks are dispersed across the locale, each incised with acute right angles and sleek apertures resembling machine work. Some weigh in excess of 100 tons, yet they were assembled with astonishing accuracy considering its origins trace back to 500 CE (Picture: Getty Images)
Puma Punku, Bolivia
The precise carving techniques of these immense slabs remain elusive, as does the identity of those responsible for their transportation. A task rendered even more challenging given their elevation of approximately 12,000 feet above sea level. The artistry possesses an industrial quality, incongruous with ancient methods. Are we witnessing remarkable ancient prowess here? Or the creation of a certain interplanetary construction company? Indeed, it’s the former, isn’t it? Even so, a celestial building project is still a rather delightful idea (Picture: Getty Images)
Stonehenge, England
Those gargantuan standing stones situated on Salisbury Plain in Wiltshire, England, have consistently perplexed individuals ranging from druids to data specialists. Constructed circa 2500 BCE, the bluestones were somehow transported eastward from quarries in Wales, a distance exceeding 150 miles, well before the advent of wheels or cranes. Furthermore, its configuration aligns precisely with the midsummer sunrise and winter solstice. This alignment is undoubtedly deliberate (Picture: Getty Images)
Stonehenge, England
For a contingent of Neolithic farmers and proto-stone masons, it represents an impressively vast, accurate and selectively-sourced celestial calendar. Which is not to say they were incapable. Or that an amicable 4ft green surveyor featuring enormous black eyes dropped by wielding a protractor and some teleporting tractor beams, naturally. But you cannot contend that Stonehenge does not constitute something of a mystery (Picture: Getty Images)
Machu Picchu, Peru
Poised high within the majestic Andes Mountains, this Inca citadel appears to sprout directly from the mountainside itself. Erected during the 15th century, its stones interlock so impeccably that a sheet of paper could not be inserted between them. The terraces, temples and stairways are undeniably earthquake-resistant and flawlessly aligned with the sun’s path (Picture: Getty Images)
Machu Picchu, Peru
It is challenging for certain individuals to accept that ropes, ramps and sheer determination yielded something so refined and precise. That, alongside considerable manpower. Or might it be alienpower? Merely if aliens ever fashioned a luxurious retreat boasting panoramic vistas, it’s tempting to envision a result resembling this to a considerable degree (Picture: Getty Images)
The Moai of Easter Island, Chile
Hundreds of immense stone effigies gaze silently across a secluded Pacific island, with some exceeding 30 feet in height. Sculpted between 1250 and 1500 CE, each ‘Moai’ embodies an ancestor, yet the genuine puzzle lies in their means of transportation. The island possessed limited trees, no wheels and scant manpower (Picture: Getty Images)
The Moai of Easter Island, Chile
Local lore asserts that the statues ambulated to their locations through spiritual force. Others speculate that they were gently levitated by extraterrestrials equipped with advanced lifting apparatus. The reality is undoubtedly more modest, though no less remarkable; it represents an extraordinary accomplishment for an isolated community in a remote setting (Picture: Getty Images)
Sacsayhuamán, Peru
Overlooking Cusco in Peru, this striking and intricate fortress composed of colossal interlocking stones is a masterpiece of Incan architecture. Certain blocks – unbelievably – weigh upward of 300 tons, shaped into elaborate polygons that interlock without a trace of mortar. The walls have withstood centuries of seismic activity without budging an iota. If only all contemporary constructions adhered to such standards, eh? (Picture: Getty Images)
Sacsayhuamán, Peru
The means by which those who oversaw Sacsayhuamán’s construction achieved such precision utilizing rudimentary hand tools remains speculative. Unless, of course, they possessed access to some otherworldly stone-cutting innovation. A smattering of anti-gravity would certainly have been beneficial in lieu of cement (Picture: Getty Images)
Göbekli Tepe, Turkey
Concealed beneath the mountain foothills of southeastern Türkiye, this site revolutionized archaeology. Originating circa 9600 BCE, it predates Stonehenge by more than twofold. Its towering T-shaped pillars bear carvings of foxes, serpents, and vultures, all arranged within enigmatic circles. It’s quite notable. Given its age, it’s utterly astonishing (Picture: Getty Images)
Göbekli Tepe, Turkey
To put it simply – this artifact ought not exist. Humans were not anticipated to construct anything of this complexity prior to the development of agriculture or writing. Thus, who devised the blueprints? Perhaps early hunter-gatherers were not solitary when inspiration struck. Or maybe they had subcontractors stationed in the skies above, available for consultation and expertise (Picture: Getty Images)
The Yonaguni Monument, Japan
We’re venturing underwater for our penultimate selection here. Uncovered by a diver as recently as 1986, this sprawling submerged structure near Okinawa showcases terraced steps, columns and platforms with sharp edges. Some suggest it’s a naturally occurring rock formation shaped by tectonic forces. Others maintain that it’s a submerged metropolis predating all known civilization. Universally acknowledged is its perplexing nature, with limited understanding of its composition or origins (Picture: Getty Images)
The Yonaguni Monument, Japan
Should this entity be man-made, it is at a minimum 10,000 years of age, which would fundamentally reshape the historical narrative for that region. If it’s a natural occurrence, it epitomizes the most conveniently geometric coincidence ever fashioned. Irrespective, The Yonaguni Monument would not appear incongruous on another celestial body. And – who can say? – perhaps a sound justification exists for this (Picture: Getty Images)
Teotihuacán, Mexico
Formerly among the globe’s largest metropolises, Teotihuacán thrived and flourished over 1,500 years ago, predating the arrival of the Aztecs. Its extensive Avenue of the Dead is flanked by pyramids that exhibit precise alignment with cosmic patterns and the cardinal directions. Reminiscent of the equally be-pyramided Valley of the Kings in Ancient Egypt (Picture: Getty Images)
Teotihuacán, Mexico
The identity of its builders, and the reason for the city’s abandonment, remain shrouded in mystery. The design possesses such mathematical rigor that some posit its architects must have operated with a certain cosmic blueprint. Perhaps those on the earth were not merely observing the heavens, but instead working from initial designs bestowed upon them by another galaxy. Or it could be they were simply skilled at pyramid construction back in those days (Picture: Getty Images)
