These craft are numerous and vary greatly in size and shape. Some change their shape and configuration continuously as the one shown above. They are cloaked to visible light mostly. Some are huge and what might be called mother ships with lots of smaller ones flying in and out. I have read where the craft are organic in a way and tuned to a specific pilot. The are controlled by thought.
They have always been here although there may be a few more now. There are many different groups and they don't all get along with each other. This planet is currently controlled by a group of reptilians who are in turn controlled an ai. I don't know what group programmed the ai. Our military's and governments and private contractors have known and worked with them for a 100 years. They influence religious leaders also mostly with mind control
Why does the craft shown in the video move so erratically? Probably to avoid getting shot down. They travel very fast so don't blink.
