If there is one skepticism in regards to UFOs or extraterrestrial beings visiting Earth, it is that despite almost everyone in the world having smartphones with decent to good quality cameras, there still isn't irrefutable photo or video proof.
Often we get to see blurry or grainy videos and photos online of alleged UFOs doing some really mind-bending manoeuvres that are simply not possible with any technology that we have. But the authenticity of such videos is always in question.
The day when we finally have definitive proof of one or the day when extraterrestrial beings (if they exist) decide to reveal themselves in front of everyone, would certainly be the biggest day in human history. It would mark 'contact' on a cosmic scale.
But that is all still speculation. As of now, we only get small tidbits from time to time that leave us ever more excited about the existence of an extraterrestrial race.
Navy Confirms Authenticity
In 2017, three videos were released to the public by The New York Times and To The Stars Academy of Arts & Science that depicted UFOs and recently, the U.S. Navy statements pretty much proved of their authenticity.
According to official statements, the U.S. Navy designates the objects in the videos as "unidentified aerial phenomena". They also say that the videos were not cleared for public release. You can check them out in this article by The New York Times.
The reaction of the Air force pilots is telling and I personally think that this could have been a real extraterrestrial craft. A video from 2004 shows an object appear suddenly at 80,000 feet which then lowered itself to a height of 20,000 feet where it kept hovering.
So, what does this mean? In my opinion, there is definitely something going on based on the secrecy surrounding the whole thing. The military may be aware of extraterrestrial beings and it may all be being kept secret for whatever reasons!
