Can You Believe This Is A UFO, And Aliens?

I've seen strange things in the sky I can’t explain, but I've never seen anything like this.

 

Knowing that some amazing things can be done in video post production, I am doubtful. But, I am also a romantic and I want to believe that we are not the only beings in the universe.

How much proof would you need?  Do you think this is authentic footage?
