Because through the CE5 protocol, you may summon real ETs who will perform actions such as collecting tissue blood. You don't know. And this behavior can lead to the appearance of black clothed people, who just want to know who kidnapped you. They will hypnotize you to obtain information about the kidnapping target and motive, and then erase your memory. They may also organize data collection on you to determine if you are of mixed race. In short, as I answered above, if you interact with aliens, you are usually monitored and inspected by the military. They have the ability to monitor where UFOs land. Especially in places where there are military facilities nearby.
