See my edited comment – they have a photo of contact with a tribal people, there are many tribes on the Andaman Islands, not just the Sentinelese, and there is no documented contact between the Sentinelese and outsiders since 1880, which was just an abduction, not really contact.
The photos here appear to show contact with a Jawara tribe, and are incorrectly labeled as Sentinelese.
Right, and I am arguing that these are incorrectly labeled because there's no authentic source showing such contact, so something has been lost in translation wherein Andaman Islanders are being called Sentinelese.
Do you have any source for those particular photos and videos being from the other Andaman islands? I've seen the video before and it was labelled then as being of the Sentinelese. I feel that if it were of a different tribe, then you'd be able to find the original context and the actual tribe it was.
There are lots of photos of the other tribes, honestly, the garb they wear is pretty similar, so I don't think that would refute anything. All I want is some more official documentation of this interaction.
If the Indian government just sent people over to throw coconuts onto an island and didn't have any official documentation of the trip, or research that the trip resulted in, a story about it more than 20 years later doesn't hold a lot of weight for me.
As you can see, this is just me being a bit pedantic, so if others want to take this as a source of truth, they are welcome to do so, I'd just like to know why they think this is authoritative.
