He's a native of North Sentinel Island in the Indian Ocean

Do you see this boy...?

He's a native of North Sentinel Island in the Indian Ocean. His island is under the special protection of the Indian government. They try to kill (and sometimes succeed!) any foreigner foolish enough to set foot on their small island. As an Indian government military helicopter is flying overhead, this North Sentinalese boy tries to shoot it down with his bow and arrow. He's also a little hard to see here, but he's probably naked. Why?

Because they probably haven't changed their lifestyle in nearly 40,000 years. This is a hominid whose lifestyle hasn't "advanced" since the Late Paleolithic. Jokes aside, and in all seriousness, this man may be technologically behind the last Neanderthal who died on this planet (also about 40,000 years ago).

So what's the point? Simply this:

Any wise "alien" (extraterrestrial) who figured out how to get here from there in less than three human lifetimes will be so thousands or millions of years ahead of us that to them we might as well be ungulates.

The only way humanity could “survive” would be on alien conditions, not ours.

How long could this boy and his village survive in a war with a modern, 21st-century army that is bringing all its technological toys to the table?
