they are the stage where they dont make fire but wait for lightning strikes and keep the embers as long as they can. Making fire is not a skill automatically known, modern white people do not automatically know how to make fire in the wild.

We know erectus knew how to do it, or at least some of the groups there knew but at this level of technology this is the kind of knowledge that can easily be lost and rediscovered many times. They have no way to record knowledge.

Come on, these guys left Africa when? Even the aboriginals who left earlier know how to do it.

What I'm saying is that making fire was and still is fundamental to survival. You need to cook meat to survive, you need fire in the night to ward off predators. It's a bit puzzling they skipped that, how do they eat raw meat with all the parasites in a tropical region especially? How is it everyone around them can make fire, didn't they trade, or exchange info. It almost seems like they are artificial, either that or they aren't human.

You sir, are retarded. Not every group of humans instantly discovered fir at the same moment. We have found A FEW instances where humans might have started there own fires in the time of erectus, that does NOT mean every human at the time knew how to make fires. The same way wheels had not been invented in the new world when europeans arrived, you still see charity adverts on TV where africans carry water on their heads because they are yet to invent the wheel. An archeologist who dug up stuff in europe from before the voyagers of exploration would ONLY have proof one particular group of people, or across one area, wheels had been invented, they would be wrong to think humans in the new world had to.

We don't know if their ancestors started their own fires, even if they did the knowledge might have been lost through death of the person(s) who knew how to do it/not passing on to next generation/ not having the resources/not needing to anymore. The steam engine was invented in ancient greece (called an aeolipile), but the knowledge was lost, then it was 'invented' again in britain in the 1800s.

The meat they would it does. Herbivore game meat has some nasty parasites, tapeworm, roundworms, anthrax, etc especially if isolated to thrive in an island. Then there's raw fish with salmonella and other brain eating worms that live in marine fish. Then there's the dangers of leaving the meat to fester out in the open when drying it. You've got nasty bacteria like e coli that thrives in such conditions.

And no, the world was not a densely populated bastion of technological advancment, so people had no 'technologies' to share with eachother anyway.

well I can guarantee you they are eating raw meat and fish all the time since these guys have fire only periodically.

You've not answered my question, they're the only ones who don't have fire among all human cultures, even the remotest aboriginal or the host of tribes in the amazon can make fire. Plus they still expect lightning, so they know what fire is. Plus they have spears which are pointed tools which Homo erectus also had access to in addition to fire.

They migrated about 60kya, so by your assumptions, humans already had fire and were accustomed to eating cooked meat. Heck most if not all tribes would have had a name for fire and a well known method to make it since most ate meat at least once a week. How do you forget your own language and how to recreate a weekly process? How do you retain the knowledge of making spears but not making fire? You could also make fire with wood not stone alone.

They are a good example of how that happens but we have pure conjecture at this point because who the fuck knows how they ended up there in the first place. Two things though.

There are a couple dozen of them out there, max estimates are a couple hundred, thats very few people. Second, the island itself is very small. You need wood of varying hardness to make fire, or proper stone like flint. Most important of all, once you know that fire is something that happens during a storm it is actually a rather hefty cognitive leap to go and figure out you could fucking make fire yourself with a bunch of sticks or stones.

I don't have a problem with making fire from first principles. My problem is the story behind how they could have lost it. And how isolated they're from the rest of humanity, not just in geography but knowledge too. It's unintuitive and the explanations offered here do not follow given what we know about human beings. It's almost as if an entire population woke up and forgot. I think it's too artificial of a scenario.

Given how dull their island is its hard to believe they stay there of their own volition (although they have boats, no idea if seaworthy ones), we also dont know just exactly how long they've been there, although the earliest we know of them is 1771 so thats a fair bit of time. People have always travelled these waters heavily, even erectus has sailed them as evidenced by homo floresiensis, so its not hard to see how a group of them could simply shipwreck in large enough a number to survive and get stranded.

Aside from all this it is CONFIRMED THEY USE FIRE they have firepits, build bonfires and shit so it could just as well be are engaging in complete wankery just because someone is like
>nuh uh they cant make fire cause sure aint nobody seen em do

Lastly, they have had a large modern freighter in shallow water right off the shore for 40 years now, MV Primrose, so I dont really think they qualify as uncontacted by now really, they can easily access it and have been known to fashion weapons from shit they found there.

off topic:
since abborigines are estimated to have left africa 50000 years ago, and since their lifestyle is virtually not progressed and their current IQ average is 60, that should mean than 50000 years ago the inhabitants of africa also had similar IQ,which is also about the time europeans migrated to europe, meaning abbos and africans are of about the same intellect as 50000 BC europeans?
