A leading scientist who worked with the Pentagon’s secret UFO division for decades claims he has personally seen proof that aliens have visited Earth, with the evidence hidden by the US Government.

According to astrophysicist Dr Eric Davis, who specialises in advanced aerospace propulsion, said he has personally seen classified photos and records that confirm not one, not two, but four different alien species have crash landed on Earth.

Dr Davis claims the corpses of at least four distinct species go alien life are being stored in top-secret facilities across America. He added that the location of the alien bodies did change during the Obama Administration.

Dr Davis told NewsNation’s ‘Katie Pavlich Tonight: “There’s a minimum of four that we know of. I’ve seen the evidence, I’ve seen the records.”

He explained the Greys to the aliens commonly represented in science fiction, like in the film Close Encounters of the Third Kind. They’re essentially a small, grey-skinned humanoid shaped with large heads and black eyes.

Meanwhile, the Nordics were described as looking like extremely tall Scandinavians with blonde hair and the most human-like features of all the alleged alien races.

There’s also a race of insectoid aliens which look like massive, human-sized praying mantises, and a species called the ‘Reptilians’, with their particular coming moniker down to their humanoid-lizard-like appearance.

Despite Dr Davis’s public claims and the ongoing rollout of previously classified files related to UFOs and extra-terrestrial life, both the White House and the military have maintained that there is no physical proof that alien life exists.

Dr Davis added that the photos and records he was permitted to see were classified, with no chance of them being released for decades with any UFO disclosure releases.

“Those are still classified, and they are not subject to the Freedom of Information Act because they’re probably classified for a 50 to 70-year period, 75-year period I believe,” Dr Davis said on Monday (August 17).

Dr Davis also admitted he was no longer “on the inside with the Department of War”, adding that he was not satisfied with the speed of the Pentagon’s UFO documents team or the information that has been released so far.
