UFOs are exactly what the term means, UNidentified Flying Objects.
It does not mean that they are from another galaxy and have almond shaped eyes.
Ask yourselves one simple question:
When did we begin seeing lots of UFOs?
Answer: Just after WWII.
Probability: The Turbo Jet engine was invented in the 1940s and the Nazis used them in combat, plus the V1 and V2 rockets.
Most of these sightings from about 1955 onward were actually secret “black” USAF and CCCP experimental aircraft including actual flying saucers so they are all man made.
Ever notice that ALL UFO discs, spaceships and objects are ALWAYS blurry images? Ever see a crystal clear image? No.
The other issue is with charlatans and boggey monster people who make money on all this rubbish.
Get off it folks. In all probability there is intelligent life out there but all these UFOs are BS.
People very much want to believe in them so then they exist behind government cover ups like Area-51 which is a secret proving grounds for experimental military aircraft. What is the big deal then?
There have been drawing on caves wall of what appears to be UFOs. It's all documented, people have been seeing them long before WWII.
