Any citizen of our planet can legitimately ask himself the questions: What are UFOs? How can they come to us? How do they work? Are there exocivilizations present on Earth? Why don't visitors from beyond space show up? Why don't governments communicate on this subject? Are we at risk of being invaded by aliens? What do they come to Earth to do? What is the link with the Crop Circles? So many questions that can make us think about our own evolution.
