There are a few types of simple life forms in our atmosphere. Only three can be seen clearly from my photos, one of which I call the dolphin head, the other is probably described by Chinese legends which I can not give a proper name.
They have varying sizes like beans, peanuts, eggs, a basketball or a giant. The smaller ones usually have a big population, I am not sure about the sand size type, are they related to those bigger size? That may need a further study.
Most of the time they will not show their face. Except when they want you to see them. They are surrounded by glowing light or have a completely transparent look. That is how for these 60 years people have been confused by their shape, thinking they are all fly saucers. I wonder why abductees never mention and never get any information from the humanoid alien about them.
People will not get tired calling them domes, cigars or disk craft. They do not want their dream to be broke. Until those space fellows show their face publicly.
