There is an island between Myanmar and Indonesia. It is called North Sentinel Island. In fact, the Sentinelese people know almost nothing of the outside world. They
have never seen a cell phone, a car or even a book. It is believed that the Sentinelese first came to the island around 60,000 years ago from Africa. Over the years, people from the outside
have tried to visit the island, but each time they have been met by attacks.
The Sentinelese do not welcome any kind of contact with the outside world. Because of this, we know little about them. We know
nothing about their culture, their language or even how many the population of the island is. There could be only 40 or as many as 400.
The island is under the control of India now and the Indian Navy maintains a 5-kilometer zone around the island, which makes it practically impossible for anyone to get to the island.
