A future extraterrestrial invasion would be "game over" for Earth as the super-predator technology aliens would possess could “wipe out life in a heartbeat”, a UFO expert warns.
Nick Pope, who investigated UFOs for the British Government, warned that humans are likely to encounter aliens that are millions or billions of years ahead.
He told The Sun that the technology gap between the two species would be “unimaginable”.

“If we face an alien invasion, it would be stealth fighters against bows and arrows, and even that is understating the technology that they would have.
“Their technology would be indistinguishable from magic. It’s almost unimaginable.
