Yeah that's right Shoubadoo,
I wasnt aware of any developing technology of this type without having serious conflict with other tribes in the area or having expansive war fare in mind, which is usually what drives technological advancement, this is what lead me to believe that they may have come in contact with other tribes or at the very least been discovered but have been ignored because their part of the Amazon is not to be bulldozed.. just yet.
Also, to be fair- we arent talking about some advanced longbows or curved hornbows or anything, just simple basic bows.
As for the bow and arrow question, think about it this way, think of the humans as one big tribe, now how did they get the bow and arrow technology? Martians? Gorrillas? Dogs? Nope, these were invented. I don't see why a tribe of people can't invent a simple bow and arrow without having to resort to war.
Anyway, I think when they mean uncontacted, it means uncontacted from the industrialised world, which is totally possible. The Earth is big enough to sustain 8 billion humans, it's just that the 6 billion around today are squeezed into concentrated places. Brazil, Indonesia, all have deep jungles that nobody could be bothered to go into, what's the point these days?
This looks exciting, I don't see why people doubt the validaty. Is Earth totally conquered by humans? There are no places that humans have never been to? We know everything about planet Earth? Of course not.
