00:00In 2018, a young American was killed on a beach by a tribe that has never once been contacted.
00:04He wasn't the first. He won't be the last. Because for 70,000 years, every outsider who
00:10set foot here has been met with one answer, arrows. This is North Sentinel Island. A speck
00:15of land in the Bay of Bengal, smaller than most cities, home to a people who have refused the
00:19entire modern world. No writing. No farming. No metal tools of their own making. And yet their
00:26arrows, we now know, are tipped with iron. So where does an Iron Age tribe get iron,
00:31on an island they never leave? The answer lies at the bottom of the sea. Push the clock back 70
00:36,000
00:36years. The Earth is in an ice age. Sea levels sit more than 100 meters lower than today.
00:42A group of early humans walks north from Africa, along the coastlines, across the Arabian Peninsula,
00:47through South Asia. Until they reach the Andaman Islands. Back then, the sea has retreated so far
00:53that North Sentinel is almost connected to the mainland. You could nearly walk there. So they
00:58do. Then the ice age ends. The oceans rise. The path back is swallowed by water. And just like
01:05that, a people are trapped on an island 60 square kilometers wide, cut off from the rest of humanity
01:09for 70,000 years. Think about that number. We invented writing 5,000 years ago. We built the pyramids
01:164,600 years ago. These people have been on this beach since the Stone Age, living off wild fruit,
01:21hunting sea turtles, fishing with bows and spears, sleeping under lintus woven from grass.
01:26And still, their arrowheads are made of iron. How? In August 1867, an Indian merchant ship called
01:32the Nineveh Rex on the reefs near North Sentinel. 106 survivors scramble onto lifeboats and wash ashore.
01:38They think they're saved. Instead, dozens of naked islanders burst from the trees, armed with spears
01:45and bows, and drive them back into the sea. The captain's report is remarkable. He notes their
01:50short hair, the red paint on their noses, and one detail that would puzzle scientists for a century,
01:54their arrows appear to be made of iron. This is 1867. The island already had iron. The theory is
02:01simple and brutal. The coral reefs around North Sentinel are a graveyard of shipwrecks. These islanders reject
02:07every human contact, but they never rejected the iron that floated in. Hull fragments. Nails. Plates.
02:14They cut it, hammer it, and turn the scrap of the industrial age into their own arsenal.
02:18In 1880, a British colonial officer named Maurice Portman lands with a search party.
02:23After days of hunting, they capture six islanders, an elderly couple and four children. Portman orders
02:28them taken back to Port Blair for study. What happens next stuns everyone. Within days, the old man and
02:34woman are dead. Not. From violence. Not from hunger. From a common cold. Their immune systems had never
02:42met a modern pathogen. A sniffle that means nothing to us was a plague to them. Portman rushes the four
02:48children back to the island with a pile of coconuts and cloth as compensation. In his 1884 report,
02:53he writes that they were terrified, refused all contact, and made no attempt to communicate. From that
02:58moment on, the North Sentinelese answer to outsiders would be a single word. No. In 1956, two Indian
03:05fishermen drift into the island's waters. The next day, their bodies are seen half buried in the sand.
03:10The Indian government responds with a law, no one may come within five kilometers of North Sentinel
03:14Island. But one man refused to accept it. His name was T. N. Pundit, a researcher with India's
03:21anthropological survey. Starting in 1967, he sails toward the island again and again, carrying coconuts,
03:27iron pots, gifts. Every single time, a volley of arrows drives. Him back. In 1974, he returns with a
03:35National Geographic film crew. The cameras are rolling when an arrow slams into a crew member's thigh.
03:40The team evacuates. But Pundit doesn't give up. He changes tactics. He never lands. He never gets close.
03:48He stops his boat just outside range, drops coconuts into the water, and turns around.
03:53If once doesn't work, twice. If twice doesn't work, ten times. He does this for 24 years. Then,
04:00on January 4, 1991, something impossible happens. Pundit's boat stops at a safe distance.
04:06He pushes coconuts into the sea. But this time, the islanders don't fire. One by one, they wade into
04:13the water, some carrying bows, some empty-handed, and take the coconuts from his hands.
04:17It is the most peaceful contact in the entire history of this island. Pundit later recalled
04:22standing waist-deep in the surf, handing out coconuts, and being told, gently, that he still
04:26could not set foot on their shore. One detail is worth remembering. He once tried to deliver a
04:32live pig as a gift. The islanders killed it, and buried it in the sand. After that, Pundit brought
04:37only coconuts. It didn't last. In 1997, the Indian government halted all contact missions.
04:44Pundit was forced to retire. In a lifetime, he never once set foot on the island. And the island's
04:50most dramatic chapter came in 1981. On August 2, a 16,000-ton freighter, the Primrose, runs aground
04:56on the reefs in a storm. Thirty-one crew members, mostly Chinese and Burmese sailors, are stranded
05:01aboard, helpless. On the third day, the captain looks out from the deck and sees something that
05:05freezes his blood. Fifty or more islanders, armed with bows and spears, are building boats on the shore.
05:11He sends an urgent cable to his shipping company in Hong Kong. Fifty savages, he writes, carrying
05:16various improvised weapons, building two or three wooden boats. We fear they will board at sunset.
05:22The crew arms itself with flair. Guns, axes, iron pipes, and stands watch around the clock.
05:28For days, the only thing that saves them is the weather. The huge waves whipped up by the storm
05:33make it impossible for the canoes to reach the ship. A week later, an Indian Navy helicopter finally
05:38arrives and evacuates every man aboard. No one dies. But the wreck of the Primrose is left on the reef
05:43forever. Over the following years, the Indian government authorizes salvage crews to recover
05:48the wreck. The workers report that the islanders come out two or three times a month, standing on
05:52the beach at a distance, watching. As long as you give them bananas, they keep their hands off you.
05:57But they are obsessed with metal. And from that point on, the arrowheads found on the island are
06:02made almost entirely of steel. The wreck of the Primrose becomes their weapons factory.
06:07On December 26, 2004, the Indian Ocean tsunami tears across the Andaman Islands. Tens of thousands
06:13die. North Sentinel takes the full force of the wave. The government sends a helicopter to survey
06:19the damage, certain that the few dozen people on the little island are gone. The helicopter reaches the
06:24shoreline, and a lone islander charges out of the trees, draws his bow, and fires straight at the
06:28aircraft. Not only were they alive, they were untouched. Scientists later concluded that the
06:33North Sentinelese had somehow sensed the tsunami from the behavior of animals and the strange shift
06:37in the sea, and moved inland to higher ground in time. A skill we, the modern world, have completely
06:42lost. 70,000 years of isolation preserved an instinct we bred out of ourselves. Now, back to the beginning.
06:49In November 2018, a 26-year-old American missionary named John Allen Chow pays fisherman to smuggle him
06:54near the island. He paddles ashore alone in a kayak and shouts to the islanders that his name is John,
06:59that he loves them, that Jesus loves them. The answer is an arrow, straight through the Bible in
07:04his hand, piercing page 453 of the Book of Isaiah. He flees back to the boat and writes in his
07:09diary
07:09that people may think he is crazy. That night, on the last page, he writes, God, I don't want to
07:14die.
07:15The next day, he goes back. The islanders shoot again. He loses his kayak and swims back.
07:21On the third day, he makes his final landing. The fishermen watch from a distance as the islanders
07:26drag his body across the sand with a rope. His remains have never been recovered. The Indian
07:31government refuses to send anyone to retrieve them, reasoning that they will not put rescuers
07:35and islanders in danger for a single corpse. But the story doesn't end there. On March 29,
07:402025, a 24-year-old American influencer named Mikhailo Polyakov sets out with an inflatable boat,
07:45a GoPro, a GPS, and a single can of cola. He studies the tides and currents. He scouts the
07:52location in October 2024 and again in January 2025, until staff at a hotel catch him and talk him out
07:58of it. On his third attempt, in March, he makes it ashore. He spends about five minutes on the beach,
08:03leaves a coconut and a can of cola, and blows a whistle for nearly an hour, trying to draw the
08:07islanders out. No one comes. He films, collects sand samples, and leaves. Two days later,
08:14he's arrested in Port Blair. He faces charges under India's tribal protection law, with up to eight
08:19years in prison. But what truly enrages scientists isn't his recklessness. It's the cola. A 21st
08:25century soft drink, left on the territory of a people whose immune systems remain frozen in the
08:29Stone Age. The bacteria on the can. The chemicals in the drink. Even the metal lining of the aluminum.
08:36To them, any of it could be lethal. The lesson of 1880 was not clear enough, too healthy.
08:41Adults, killed by a common cold. One can of cola could be more dangerous than a plague.
08:47Now you understand why the Indian government drew a five-kilometer exclusion zone around North
08:50Sentinel, why the Navy patrols it around the clock, and why the law allows up to seven years in prison
08:54for anyone who approaches without permission. It isn't to protect you. It's to protect them.
09:00This is a people who, on an island of 60 square kilometers, survived the Ice Age, survived colonial
09:05invasion, survived two world wars, survived the Indian Ocean tsunami. For 70,000 years,
09:10they have never once asked the outside world for help. But there is one thing they may not survive.
09:15A man with a phone, chasing followers. The North Sentinelese don't need our civilization.
09:20They don't need our religion. They don't need our cola. They need exactly one thing,
09:25and it is the one thing we refuse to give them. To be left alone.
09:42The North Sentinelese don't need our religion to learn.
09:43It is the one thing we refuse to follow on the island.
09:43It is the one thing we refuse to share.
09:48After the release of the people, we have no control of the earth.
09:49The North Sentinelese don't want to worry.
