This is a photo of a UFO seen over Mexico, apparently composed of innumerable spheres. These are called EBANIs by Mexican UFO researchers. They squirm like snakes in the air, as shown by the movement it has made in a short time in this second photo. They are not the result of hand-held long exposures of lights in the sky like I used to think, but they appear during the day and are stable structures. Spheres are often seen coming off of them. It reminds one of the “flying serpents” mentioned in ancient literature.
This video linked in the blue text starts out with easily explained UFOs and then goes into these things.
