I can remember seeing the above picture many years ago and found it intriguing. I had also seen where some people thought that the dark figure was, or at least could be, a Bigfoot. Of course, we know that the dark figure is not a bigfoot but a person.
This image is from a very isolated tribe. In fact, this tribe is considered one of the world's last uncontacted peoples, even though there has been some contact with them over the years.
