Things like big-footed modern-day barbarians and this time “lost Amazon tribe” are around in media reports. I don’t believe they are true or completely true even though they might appear in “mainstream” media outlets or are re-run in other equally “authoritative” ones.
We have to develop a sense of humor and have our own judgment when being inundated by information. I had no proof they were just cooked up. But, the picture didn’t look to me more real than Hollywood movies. Also, I don’t believe there are any areas where non-barbarian humans cannot reach on Earth, especially where there are trees in the Amazon and where there are more than 90-percent-naked tribesmen.
Here is what we now know about the photo now – it’s a hoax and it’s half-truth. The tribe has been known from 1910.
