Not aliens, just an uncontacted tribe

BBC News has images from the Brazil National Indian Foundation of an uncontacted tribe that lives along the Brazil-Peru border. First of all: cool. Second of all: there are still uncontacted tribes? Third of all: Is it just me, or do the images make it seem as if they're a species on an alien world being visited by us?

It's the aerial perspective, I guess, not to mention the fact that their bodies are covered in red and black paint. Every time I see one of the men wielding an arrow or spear at the photographer-interlopers, I wonder what they're thinking. Do they think the helicopter (I assume the photographer(s) travelled in a helicopter) comes from the gods? Another planet? Other civilisations?

It boggles my mind to think that I'm sitting here, blogging about this, a blog post which could potentially reach any wired person in the world, while talking about it on IM and Facebook --- and I'm looking at an uncontacted tribe.

Okay, I'm going to go look at the images some more ...
