Aliens have always been on Earth and live under the ocean for protection, according to claims made by a UFO expert.
Anna Whitty, the author of 'UFO's: A Fundamental Truth', claims that aliens are actually human beings in very advanced form.
She has made the claims based on the testimony given by Dr. Shirley Wright - a former colleague of Albert Einstein who said that she had interviewed extraterrestrials at the site of the Rosewall crash in 1947 - who claims that the aliens asked "how far into the ocean" humans had explored.
Whitty told the Daily Star: "I do think they've always been here.
"If what Shirley said is right, and as she tells it is accurate, it is more likely that aliens come from somewhere under the sea or caves or something like that, rather than another planet.
"It makes sense, because there's a lot of evidence on the planet that there has been a massive cataclysm every few thousand years."
