crazy

I was just on Yahoo and looking at the pictures of the tribe they found in the Amazon or where-ever it was that has never been contacted by civilization. What a crazy thought! I mean I understand that they know nothing different but how does someone just grow up in total isolation and never venture out of their surroundings. How far are these people from a town? It's so weird to think that theirs a group of people out there who only know how to hunt and survive in the wilderness and do you even think they think like we do? Do they think there are other people in the world other then them? Do they know they live in a world where other people can exist?!?! It's amazing how we've been on earth for so long yet we discover new things almost every day. If you have a chance, check it out on CNN too. They say about 100 un-contacted tribes are out there worldwide and about half life in the Peru/Brazil areas.
The pictures show them shooting bows and arrows at the plane taking pictures. I wonder what's going through their heads when this big white thing flies over their homes and they have no clue what it is. I'd probably try to find a bow and arrow to shoot at it too.
