2 types of UFOs. 1 is man made by black projects from US military from Project Paperclip from after WWII and also includes NASA. 2nd type is demonic and are controlled by the Fallen Ones, the Nephillim. They most likely took up residence on Niribu (12th planet) after they destroyed Mars. Bible speaks of them and even mentions them as the frog people that come from the water. Hence why we know them as the reptile aliens. The grays I won't get into here.
But actual little green men from a distant star, no. Green men from ancient past that still live in our oceans and on another planet that work with Lucifer and do his deeds on earth, yes.
Black holes are not holes, but rifts in space and time. They are access points to more dark matter, where Lucifer gets his strength from and dark matter is also what powers most UFOs. They went from old Rolls Royce and BMW engines (both manufacturers have records) to graviton engines to black matter engines. Even NASA has a black matter engine so don't think I am a lost soul, I know more than most could handle. Look into the new ion motor and realize its a black matter motor.
People should study the bible more, it tells us all about them. Its what made me a believer.....30 yrs as agnostic/atheist and due to deep deep DEEP research on UFOs, 9/11, mind control and about 27 other topics, the research led me to the bible, then once I understood that past what most think it is, the truth showed itself. When people say the bible stands for " Basic Instructions Before Leaving Earth" they are NOT kidding.
The ball UFO is nothing more than another Nazi copy and also a copy of Sputnik, Russia's satellite. The balls are used by CIA and FBI for observation and tracking. We are tracked more than most even can comprehend.
Cell phone technology was invented in the early 1900's and sezied by the military. In the 1940's the military had computer systems that could track every phone call on the planet and record anything due to keywords mentioned. Today, you are so tracked and so known that they know more about you and your thinking patterns than you do yourself. Ever wonder why marketing does so well? Stealth was invented and flying in the 50's, when we had black and white TV and AM radio. Yet its still advanced today. Imagine, try to imagine if you can what they have today.
Even the ex CEO of Boeing is on record stating " anything you can even imagine flying, we already tried it all and more prior to 1947 ". Even Donald Rumsfeld is on video from 1992 stating the entire moon landing and most of NASA is a hoax and just a cover up to hide people from the truth.
I will tell you this much, ever see one land....run. Whether military or Nephillim, they are not there for the good of you. The Nephillim use to eat humans as food prior to the days of Noah's flood. Why do you think we have abductions and birth items? They are growing their own food.
