The angle of the shadows is the most obvious clue for it being a fake.
The shadow of the threes is almost at an angle of 45º.
The shadow of the UFO, not only does it look brighter than the shadows of the trees (that are not completely opaque as the UFO), the angle is higher,
as if the Sun was higher in the sky but only for the UFO.
Also, there is the not small fact that
jkrog08 found a video with both versions, with the UFO and without the UFO,
here.
Please see it till the end.
