This footage appears to be a telescopic shot of the moon in daylight. The camera zooms in on the sharply-lit crescent horizon. This reveales several objects apparently flying close to its surface, casting convincing shadows as they move from sunlight into darkness. The objects are clearly miles long, given the scale involved and the shadows cast. It's the only video on the channel, named Jean-Michel Tenac.
Possibilities:
1) Fake. Too lucky, not to mention the "I'm real!" camera shake and mic spike. Here's a recreation by a 3D animator, shpwing how it might have been created with CG. It isn't as convincing as the "original", but is an effective demonstration of technology and technique.
2) Aliens. They're sick of watching us do this to ourselves and are coming to help/destroy us.
