Could there be a tribe in the Amazon we know nothing about in this day and age?

I think I am calling faked.

I received this video from a FB friend and they swears that it is a true video. I have so many problems with the video.

A. People that we have never seen before? Bugs I understand but People??

B. Why is always the British people finding these tribes?

C. Why are they not throwing spears and shooting arrows at this huge metal bird in the sky?

Ok El Paso, Send in your videos be they fact or faked and let the people guess, Fact or Faked?
