The mummified remains of what looks like a 6-inch space alien has turned "Sirius" into the most eagerly awaited documentary among UFO enthusiasts.
The findings, however, might come as a disappointment.
In early publicity, filmmakers claimed the documentary would reveal that the DNA of the creature with an oversized alien-looking head couldn't be medically classified.
In fact, the film, which premiered Monday in Hollywood, features a scientist who concluded the little humanoid was human.
"I can say with absolute certainty that it is not a monkey. It is human -- closer to human than chimpanzees. It lived to the age of six to eight. Obviously, it was breathing, it was eating, it was metabolizing. It calls into question how big the thing might have been when it was born,"said Garry Nolan, director of stem cell biology at Stanford University's School of Medicine in California.
"The DNA tells the story and we have the computational techniques that allows us to determine, in very short order, whether, in fact, this is human," Nolan, who performed the DNA tests, explains in the film.
"Sirius" focuses on the remains of the small humanoid, nicknamed Ata, that was discovered in Chile's Atacama Desert 10 years ago and has, literally, gone through different hands and ownership since then.
