It's fake, not because aliens don't exist, but because there is no conclusive evidence.
No recorded sighting or story has ever been coupled with indisputable evidence, ever. Like paranormal sightings or experiences, really. It's always photoshopped, edited or something similar. If it's up for debate, it's almost certainly fake. Until it is, without a doubt, confirmed and proven? You should always assume these things are hoaxes.
Assuming so does not mean that you disbelieve in alien life, just these videos.
