I have personally seen many anomalous things, UAP and paranormal related, but until I actually can interview the occupants I reserve my opinion of who and why. ( I was Montana State Director and lead Field Investigator for MUFON for a few years.)
I can state that the historical accounts of sightings falsify the logic they are today's technology, with the caveat that statement excludes the possibility of time travel.
For the best answers I can provide I direct you the excellent study done by Reinerio Hernandez J.D., titled "BEYOND UFOS: THE SCIENCE OF CONSCIOUSNESS AND CONTACT WITH NON HUMAN INTELLIGENCE (VOLUME ONE Book 1)" (https://www.amazon.com/dp/B07G3JLS3H/ref=dp_kinw_strp_1)
A Gift From The Stars: Extraterrestrial Contacts and Guide of Alien Races https://www.amazon.com/dp/B08HGLNH1P/ref=cm_sw_r_cp_api_glt_fabc_TDYD9G3XBFDVHT386AC0
this book gives you everything you need to you need to know about our world, aliens, the truth etc. It will end easy to understand and comprehend if you’re spiritually awoken to a certain level i guess. But this book is amazing and I would all if not most of ur answers will be answered.
