The Easter Island moai are monolithic stone statues carved by the Polynesian people of Rapa Nui, mostly between about 1250 and 1500 CE, from volcanic tuff quarried at the crater of Rano Raraku. Close to a thousand are known; the average moai stands about 4 metres tall and weighs around 12.5 tonnes, and the leading explanation for how they reached their platforms is that islanders "walked" them upright with ropes, rocking each statue forward from side to side.
The moai matter because they sit at the centre of two of the most repeated stories in popular archaeology. One says no small island society could have produced them; the other says the islanders built them, stripped their island bare and destroyed themselves. Radiocarbon, genetic and field evidence published between 2006 and 2025 has reshaped both stories.

Who carved the moai?
The moai were carved by the ancestors of today's Rapa Nui people, Polynesian voyagers who reached the island after crossing thousands of kilometres of open Pacific. Rapa Nui covers about 163 square kilometres and lies some 3,500 kilometres west of mainland Chile and 2,000 kilometres from Pitcairn, its nearest inhabited neighbour.
For much of the twentieth century, settlement was dated to somewhere between 400 and 800 CE. In 2006 the archaeologists Terry Hunt and Carl Lipo published "Late Colonization of Easter Island" in the journal Science, using radiocarbon dates from excavations at Anakena beach to argue that people arrived much later, close to 1200 CE. Later island-wide radiocarbon reviews have broadly supported this short chronology, and it is now the working consensus.
The islanders' language, crops and DNA all point to an East Polynesian origin, and the statues belong to a wider Polynesian practice of carving ancestral figures, here on an unusually large scale. Archaeologists read the moai as images of deified ancestors or chiefs set up to watch over the community, which is why almost all platform statues face inland, toward the villages.
How were the moai made?
Almost every moai was carved directly out of the slopes of Rano Raraku, an extinct volcanic crater whose compressed volcanic ash, or tuff, is soft enough to work with stone tools. Of the more than 900 statues recorded, all but 53 are of Rano Raraku tuff; the rest were made from basalt, red scoria and other local stone. Carvers shaped the front and sides of each figure while it was still attached to the bedrock, then cut it free along the back; thousands of basalt picks still lie around the quarry.
Nearly 400 statues remain at the quarry in every stage of completion, from rough outlines to finished figures stood upright on the slope. The largest, nicknamed El Gigante, was never detached; had it been completed it would have stood about 21 metres tall and weighed an estimated 145 to 165 tonnes. The tallest moai ever erected on a platform, known as Paro, was almost 10 metres tall and weighed about 82 tonnes.
Some statues received a pukao, a cylindrical red topknot carved from red scoria quarried at Puna Pau, a small crater on the other side of the island, and lifted onto the head once the statue was standing. In the late 1970s the Rapa Nui archaeologist Sergio Rapu and his team found that the eye sockets of statues on the platforms had been fitted with eyes of white coral, with pupils of obsidian or red scoria. Those platforms, called ahu, often held a row of statues above a burial and ceremonial area.
Do the Easter Island heads have bodies?
Yes. Every moai is a full figure with a head and torso, usually with long arms carved down the sides and hands resting on or near the abdomen. The famous "heads" photographed on the slopes of Rano Raraku are complete statues that were stood up in pits on the quarry slope and then gradually buried to the shoulders or chin by centuries of eroding sediment.
Thor Heyerdahl's Norwegian expedition of 1955 and 1956 excavated several of the quarry statues and exposed their torsos. The Easter Island Statue Project, directed by Jo Anne Van Tilburg with support from UCLA's Cotsen Institute of Archaeology, later excavated two Rano Raraku statues that had been almost completely buried by soil and rubble. One was found standing in a deep hole, and petroglyphs were exposed on its back. The project's soil work suggests the quarry slopes were also gardened, with banana, taro and sweet potato.
How did the moai "walk"?
The best-supported explanation is that the statues were moved upright, rocked from side to side by teams pulling ropes attached to the head, so that each statue swivelled forward in a series of short steps. Rapa Nui oral tradition says the moai walked to their platforms, and this method reads that tradition literally.
The idea has been tested several times. During the 1955 to 1956 expedition, Heyerdahl recorded twelve islanders raising a fallen statue of about 25 tonnes upright on its platform in 18 days using wooden levers. In 1986 Heyerdahl invited the Czech engineer Pavel Pavel to the island, and a team of 16 local residents and one leader made a 15-tonne moai "walk" with ropes tied to its head and base.
In 2012 Hunt and Lipo ran the best-known experiment. A 4.35-tonne concrete replica, built with the D-shaped base and forward lean seen on statues abandoned along the island's ancient roads, was moved about 100 metres in 40 minutes by 18 people pulling on ropes. They published the results with the Rapa Nui archaeologist Sergio Rapu Haoa in the Journal of Archaeological Science in 2013. In 2025 Lipo and Hunt followed up in the same journal with an analysis of 962 moai, including 62 found along the roads, arguing that the road statues' wide bases, forward lean and the roads' concave, roughly 4.5-metre-wide surfaces were designed for exactly this kind of movement. Critics favour sledges or wooden rails; the debate is about method, not about who did the moving.
What happened to Rapa Nui?
For two decades the standard answer was "ecocide". In the version popularised by Jared Diamond's 2005 book Collapse, islanders cut down the forest to move ever bigger statues and their population crashed in war and famine before Europeans arrived. The loss of the island's palm forest is real; the population crash is what recent research disputes.
Three lines of evidence now point the other way. First, Hunt and Lipo argued that introduced Polynesian rats, eating palm nuts, did much of the damage to the forest. Second, a June 2024 study in Science Advances led by Dylan Davis of Columbia University, with Robert DiNapoli, Carl Lipo, Gina Pakarati and Terry Hunt, used satellite imagery and machine learning to map the island's rock gardens, a mulching technique that keeps thin soils moist and fertile. The gardens covered only about 188 acres, enough to feed about 3,000 people, which matches the population Europeans reported rather than the much larger population the collapse story requires. Third, a September 2024 study in Nature led by J. Víctor Moreno-Mayar sequenced the genomes of 15 Rapanui individuals who lived between about 1670 and 1950 and found no genetic signature of a severe population bottleneck in the 1600s.
The same Nature study found that ancient and modern Rapanui carry about 10 percent Native American ancestry, introduced through contact that the authors date to roughly 1250 to 1430 CE, centuries before Columbus.
The catastrophe that did happen came from outside. The Dutch navigator Jacob Roggeveen landed on Easter Sunday, 5 April 1722, giving the island its European name, and estimated a population of roughly 2,000 to 3,000. In December 1862 Peruvian slave raiders seized around 1,500 people, about half the population; the few who were returned brought smallpox. By 1877 only 111 Rapa Nui people remained on the island. Chile annexed Rapa Nui on 9 September 1888 under an agreement signed by Policarpo Toro. Roggeveen's crew still saw statues standing, but by 1868 every moai had been toppled; about 50 have since been re-erected. In 1995 Rapa Nui National Park was inscribed as a UNESCO World Heritage Site.
What is rongorongo, and has it been deciphered?
Rongorongo is a system of glyphs carved onto wooden objects on Rapa Nui, and it has never been deciphered. It survives on fewer than 30 objects, first noticed by outsiders in 1864, and most are now held in museums and collections outside the island.
The key question is whether the islanders invented writing on their own or developed rongorongo after seeing Spanish documents during a 1770 visit. In 2024 a team led by Silvia Ferrara of the University of Bologna radiocarbon-dated four tablets held by the Congregazione dei Sacri Cuori in Rome, publishing in Scientific Reports. Three dated to the nineteenth century. The fourth, the tablet known as Échancrée, gave a mid-fifteenth-century date for its wood, with an estimated felling date of about 1493 to 1509, some two centuries before Europeans arrived. Old wood does not prove when the glyphs were carved, but if the carving was close in age, Rapa Nui would be one of very few places to invent writing independently.
Was there a lost civilisation behind the moai?
Mainstream archaeology finds no evidence that anyone other than Polynesian islanders carved and moved the moai. The quarry, the tools, the unfinished statues, the roads, the experiments and the radiocarbon dates form one continuous story that begins with settlement around 1200 CE. Older ideas of a sunken Pacific continent, such as Mu or Lemuria, are rejected by marine geology: the island is the summit of volcanoes rising from the ocean floor, with no drowned landmass around it.
What the newest research does show is that Rapa Nui was less isolated and more resilient than earlier accounts allowed. Readers comparing Pacific monuments will find a similar debate at Nan Madol, the basalt city off Pohnpei, and an older chapter of the megalith story at Stonehenge.
Billy Carson's reading
Billy Carson approaches Easter Island as part of a wider question he returns to across his work: whether the great megalithic sites of the world preserve the memory of a shared, much older body of knowledge. His position, developed in his writing and talks on Atlantis and the Anunnaki, is that similarities between ancient cultures are better explained by contact and a common inheritance than by coincidence. He has announced Rapa Nui as a 4biddenknowledge tour destination, has discussed the island in short videos such as "Did you know about what happened on Easter Island?", and gave it a segment, under the heading "Easter Island and lost global contact", in his podcast conversation with the researcher Dan Richards, "Ancient Civilizations Reset Cycles: Atlantis, Lost Knowledge and Human Amnesia Explained".
His interest in Rapa Nui sits beside his interest in the Pacific's other great megalithic site, Nan Madol, which he has discussed with Erich von Däniken on the 4biddenknowledge Podcast, and within the reset-cycle thesis he links to the Younger Dryas: the idea that catastrophe repeatedly knocked humanity back and that monuments carry fragments of what came before. That is his interpretation, not an archaeological finding, and the evidence above dates the moai firmly to the Polynesian era. The two pictures meet on the ocean itself: genetic evidence of contact between Rapa Nui and the Americas before Columbus is the kind of long-distance connection Carson argues for, though it points to Polynesian voyagers rather than a lost parent civilisation. The wider ancient-origins side of his argument lives in the Anunnaki topic hub.

Frequently asked questions
How many moai are there on Easter Island?
Close to a thousand. Counts vary with what is included: standard inventories list more than 900, a 2025 study analysed 962, and the Easter Island Statue Project has recorded more than 1,000 sculptural objects. Nearly 400 are still at the Rano Raraku quarry.
How old are the Easter Island moai?
Most moai were carved between about 1250 and 1500 CE. Rapa Nui itself was settled by Polynesians around 1200 CE, according to radiocarbon work by Terry Hunt and Carl Lipo published in Science in 2006.
Why do the moai face inland?
The moai on platforms face inland because they were meant to watch over the communities that built them. Archaeologists interpret them as images of deified ancestors or chiefs, and most platforms stand near the coast with the statues looking back toward the villages.
Did the Easter Islanders destroy their own society?
The current evidence says no. Deforestation happened, but a 2024 Science Advances study of the island's rock gardens and a 2024 Nature study of ancient genomes both found no sign of a population collapse before Europeans arrived in 1722. The steep decline came after contact, through the 1862 Peruvian slave raids and the smallpox that followed.
Can anyone read rongorongo?
No. Rongorongo has never been deciphered, and it survives on fewer than 30 wooden objects. A 2024 radiocarbon study dated the wood of one tablet in Rome to the fifteenth century, and its possible pre-contact origin remains debated.
