ALIEN Invasion or Sign of End Times: Mysterious City appear over the skyline of China [WATCH Video]

The image of a city skyline appeared floating in the clouds above the cities of Jiangxi and Foshan on Oct. 7 — and skeptics are starting to question its origin.

Scientists say Chinese residents witnessed what is a mirage called a Fata Morgana — but conspiracy theorists were quick to jump in calling it part of a secret project by NASA to fake the second coming of Christ.

The Fata Morgana is created when temperatures cause light to bounce and bend through different layers of air, Prof. Kenneth Bowman from Texas A&M University explained.

"It's not exactly a reflection because it's not a mirror but it's like looking through a lens and you're seeing the surface at a long distance away but it looks like it's floating up in the atmosphere," Bowman said.

Despite the science backing up the phenomenon, conspiracy theorists still believe the vision could be part of a suspected NASA project called Project Blue Beam — which will use holograms to simulate alien invasions or the second coming of Christ.
