In the USA, in 2007 and 2017 video clips have leaked online in which you could see UFOs.
The videos had gone viral among the public and everyone believed they were alien spaceships.
 Have a look at the video.
However nothing was proven.
The American government never responded to any of the rumours regarding alien lives they don't have any evidence.
Now the US Department of Defense (DOD) has issued a statement
over the misunderstandings in the video.
DOD said that the 2007 and 2017 videos which were leaked, were captured by US Navy Pilots in 2004 and 2007 respectively.
They said that there is no evidence to prove the theory of aliens,
the US military is studying it and trying to identify the object.
The video does not confirm the existence of aliens but people have already began spreading rumours.
