Rapa Nui: did the moai walk?
Rapa Nui (Easter Island), Chile · 27.12°S 109.35°W
Sunset, about 3,500 km off the coast of Chile. Nearly a thousand stone faces are watching the island, and the signal no longer sounds like pulses. In Ancient Signal you scan four spots on Rapa Nui through the Believer lens and the Sceptic lens, then walk a moai home with two rope teams.

The short answer
The moai were carved by the Rapa Nui people, mostly between about 1250 and 1500, from volcanic tuff at the Rano Raraku quarry, where hundreds still lie at every stage of work. In 2012 an experiment showed 18 people with ropes could 'walk' a 4.35-tonne replica upright, which fits the island's own tradition that the statues walked to their platforms.

Believer lens
Ancient Aliens presented the moai as massive sculptures made with the help of advanced technology, asking whether islanders without metal tools could really carve so many giants.
Sceptic lens
All but 53 of the more than 900 moai were carved from this crater's volcanic tuff, and 394 still lie here at every stage of work. One unfinished figure, about 21 m long, is still joined to the rock. The quarry shows the whole human process, mostly between 1250 and 1500.
Moai on the road

Believer lens
Giorgio Tsoukalos has argued on Ancient Aliens that the island's stories of statues that 'walked' describe anti-gravity technology, with the moai levitated from the quarry to their platforms.
Sceptic lens
In 2012 Terry Hunt and Carl Lipo had 18 people walk a 4.35-ton replica 100 m in 40 minutes, rocking it upright with ropes. Their 2025 study notes that statues lie abandoned along ancient roads, as you would expect if some fell while being walked.
Ahu Tongariki
East coast · 15 moai facing inland
Believer lens
To ancient-astronaut writers, raising a row of multi-tonne giants onto a stone platform is proof of lifting technology the islanders could not have had.
Sceptic lens
Ahu Tongariki holds 15 moai with their backs to the sea, watching over the land. Its heaviest weighs about 86 tonnes; a typical moai stands about 4 m and weighs around 12.5 tonnes. Only one still wears a pukao, a red stone topknot from the Puna Pau quarry; the 1960 tsunami scattered the rest.
Birdman carvings
Coastal rock · petroglyphs
Believer lens
Erich von Däniken tied the island's 'bird men' to a legend of flying men who landed and lit fires. Fans add the rongorongo script, still undeciphered, as one more mystery.
Sceptic lens
The birdman cult grew as the moai era declined, centred on a yearly contest to bring back the first sooty tern egg. About two dozen rongorongo objects survive, all now off the island, and part of one tablet has been linked to a lunar calendar.
The puzzle: Walk the moai home
At the survey table two rope teams rock a statue from side to side. Pull a rope when the moai leans fully towards that side, alternating left and right, and ten good pulls bring it home. Solve it and both lenses have their say.
What the sceptic notices
That rhythm is the method. Hunt and Lipo's team of 18 rocked a 4.35-tonne replica 100 m in 40 minutes with nothing but ropes and timing. Statues lying along the old roads fit the same story.
Questions people ask
- Who made the Easter Island heads?
- The Rapa Nui people, Polynesian settlers of the island, carved them mostly between about 1250 and 1500 at the Rano Raraku quarry.
- How were the moai moved?
- The leading explanation is that teams with ropes rocked them upright along prepared roads so they 'walked', as island tradition says. A 2012 experiment moved a replica this way.
- Are the Easter Island heads just heads?
- No. Most moai have full torsos; the famous 'heads' on the slopes of Rano Raraku are statues buried up to their shoulders by centuries of soil.
