Lots of people believe in extraterrestrial life forms, but not many can give specific details about what they look like and where they're living. But that's just what Paul Hellyer, the now-90-year-old former defense minister of Canada, did in his recent interview with Russia Today, claiming there are 80 different species of alien life, from places like Andromeda, Pleiades and Zeta Reticuli, and some look just like us.

“The latest reports that I’ve been getting from various sources are that there are about 80 different species and some of them look just like us and they could walk down the street and you wouldn’t know if you walked past one," said Hellyer, who served during the Cold War, who went public with his theories on extraterrestrial life in 2005, The National Post reported. "They are what we call 'Nordic Blondes' and also the Tall Whites who were actually working with the U.S. air force in Nevada. They’re able to get away with that; they had a couple of their ladies dressed as nuns go into Las Vegas to shop and they weren’t detected. ... Then there’s the Short Greys as they are called, and they are the ones you see in most of the cartoons, they have very slim arms and legs, they are very short, just a little over 5 feet, and they have a great big head and great big brown eyes. But there are different species and you have to know that they are different species and know that they all are different. If you saw the Short Greys, you’d certainly know there’s something up that you’ve never seen before, but if you saw one of the Nordic Blondes, you’d probably say, “I wonder if she’s from Denmark or somewhere.”

But fear not: Hellyer said most of the aliens who have “been visiting our planet for thousands of years” are “benign and benevolent, and they do want to help us, [but] there may be one or two species which do not.”

However, he does believe that these species, who have a “long history” — he said he knows of 50 reports of UFOs during the Cold War — are concerned about unconventional warfare.

“Since we invented the atomic bomb and they are very concerned about that and the fact that we might use it again, and because the Cosmos is a unity and it affects not just us but other people in the Cosmos, they are very much afraid that we might be stupid enough to start using atomic weapons again, and this would be very bad for us and for them as well,” he said.

“They don’t want to tell us how to run our affairs, they have accepted the fact that this is our planet, and that we have the right to run it, but they are very-very concerned: they don’t think we are good stewards of our planet, we’re clear-cutting our forests, we’re polluting our rivers and our lakes, and we’re dumping sewage in the oceans, and we’re doing all sorts of things that are not what good stewards of their homes should be doing. They don’t like that and they made it very clear. As a matter of fact, they have given us a warning.”

One of the most startling of all his claims, though, came about halfway through the interview when he was asked whether or not he’s ever had an encounter personally with aliens.

“Not an encounter with aliens, no. I’ve seen a UFO, about 120 miles north of Toronto, over Lake Muskoka, where I have a cottage,” he admitted. Hellyer said he and his wife had been looking at the stars when they spotted a UFO.

“We watched it until our necks almost broke for about 20 minutes, and it was definitely a UFO because it could change position in the sky by three or four degrees in three or four seconds,” he said.

Hellyer went on to say that when he was minister, he received plenty of “sighting reports,” though about 80 percent of them were “sights of Venus or of plasma or a dozen other things.”

“But there were 15 percent or 20 percent for which there was no explanation, and they were the genuine unidentified flying objects,” he added.

Hellyer said he’s hopeful someone will crack the case and share their findings with the world that aliens do exist. “There’s just so much evidence, if anybody will take time off to do a little bit of research and study…There’s just a lot of information out there and it doesn’t take very long to get your hands on it.”
