In this lecture Richard Dolan explains that the UFO phenomenon is more complex than most of us realise. There are human and non-human factions that are involved.
Imagine if a group of people produced a secret society that is way more advanced than 99,9% of the rest of us. Their knowledge on technology, science, cosmos,… is lightyears ahead of ours. They would have a enormous influence over our world.
This breakaway civilisation is also in contact with several extraterrestrial species that live on our planet. They are fighting a clandestine cold war. A lot of UFO sighting can probably be attributed to these activities.
