According to an article in the Huffington Post, the DNA for what looks like a 6 inch space alien has been classified and found to be human.

Hollywood publishers originally said that the documentary would reveal that the DNA of the creature could not be medically clasified.  In a rare stroke of honesty (much to the chagrin of UFO entusiasts), the film “Sirius” features a scientist who concluded that the little humanoid is in fact human.
