YouTube: Mavi777

Popular conspiracy theory channel 'Mavi777' has uploaded a strange clip that shows a UFO hovering in the skies above China. The video uploader revealed that the footage was shot by an aeroplane passenger from the flight KL883 which was en route from Amsterdam to Xiamen, China.

Interestingly, the shape of the UFO spotted in the sky resembled the oval-shaped flying saucers which we have seen in Hollywood sci-fi flicks like 'Mars Attack'.

The video uploaded by 'Mavi777' soon went viral on the internet, and conspiracy theorists started arguing that an alien spacecraft has reached the earth's atmosphere. A section of other people claimed that aliens have been visiting earth for many years, and they even allege that governments are aware of these secret visits.

"I can't believe people are still so shocked! These beings have been around since the beginning! People who think we are the only lifeform in the universe are still sleeping. I get it though, it is easy for them to go about life more comfortable... Or... Like me, they don't care! At any rate, good vid," commented Conor Conor, a YouTube user.

Some other people argued that aliens are working hand-in-glove with world powers like the United States and China for materializing unknown motives.

However, sceptics made it clear that the object spotted in the video could be actually a weird shaped cloud. Some other people claimed that this object could be added in a normal video using advanced computer graphics. 

The news of this UFO sighting came just a few days after another conspiracy theory channel 'MrMBB333' released a video of multiple black objects hovering in formation over Portland. Interestingly, the objects in the video were seen aligned in a triangle shape, and they remained static throughout the run time of the video.
