It's obviously not the real deal. If I saw a weird object hovering over my city, I'd do what any curious human being would do....whip out my trusty camera and drive straight to it, filming as I go. And if after getting a very close look at the object i decide that this thing is 'alien', I'd get on my cell and wake the dead with phone calls. By the end of the night, this object would be in an official police report somewhere.
I don't know anyone who would be curious enough to film this thing, but not enough to actually take a closer look. That behavior is 'alien' to me.
