True. That was highlighted in the documentary but it was mentioned that the aliens were trying to help. In one incident the radiation level went down significantly after the UFOs were seen. Also, contrary to the norm, many people felt a warm sensation of peace.
Personally I don't believe or disbelieve in aliens per se. However, I
do believe that some UFO sightings are real. There are many different explanations behind those mysterious UAPs. If someone came up to me and said they saw one, I wouldn't mock them or call them crazy.
