The world is more connected than ever before, courtesy of breakthroughs in technology, and making our tiny blue rock floating through space smaller and smaller.

And yet, there are some who still live off-the-grid, devoid of modern luxuries.

Perhaps the most notable, and infamous from an incident back in 2018 (more on that later), are the Sentinelese, a tribe of 50-150 people, living primitively on India’s North Sentinel Island. They have little, if any, contact with the outside world; they still hunt with spears and bows. But through satellite imagery, some of their secrets have been revealed.

YouTuber GEODENSITY compiled the video above, which showcases Google Earth imagery, displaying some of the Sentinelese camps, movements, and behaviors. The video also dives into the history of the tribe, dubbed the “world’s most isolated people.”

According to EBSCO, a research database, here’s a little more on this mysterious tribe:

“The Sentinelese are an indigenous tribe residing on North Sentinel Island in the Andaman Islands of Southeast Asia, known for their isolation and fierce resistance to outside contact. As one of the last uncontacted tribes in the world, little is understood about their daily life and culture due to their strong desire for privacy.

“The Indian government has established a protective exclusion zone around the island, preventing outsiders from approaching, although tragic encounters have occurred, such as the deaths of fishermen and a missionary. North Sentinel Island, part of India’s Andaman and Nicobar Islands Union Territory, is approximately 23 square miles and features dense forests and surrounding reefs, leaving it largely inaccessible.”

Back in 2018, an American was killed by the tribe when he attempted to visit them. John Allen Chau, a 27-year-old from Alabama, was a modern-day missionary of sorts, attempting to bring Christianity to the primitive people. And yet, he was warned.

"The number of people belonging to the Sentinelese tribe is so low, they don't even understand how to use money,” journalist Subir Bhaumik, who has covered the tribe for years, told the BBC. “It's in fact illegal to have any sort of contact with them."

According to a report, upon approaching the island, “[Chau] was attacked by arrows but he continued walking.” His body was spotted two days later, but never recovered.

Some mysteries are better left unknown.
