The video showing the alien was apparently taken by British tourists when they were on a trip in the Amazon Rainforest. They then handed it over to the Brazilian Government.
If you look closely at the image you can see a small grey figure just to the left of the trees, and to the right you can see a shining light. The “alien” only slightly moves, and doesn’t seem to look at the people at all, there isn’t very much footage of this so called little grey being. The footage apparently is going to be used in a Hollywood movie.
There is an article about this in News.com.au.
