Accusing world famous astrophysicist Stephen Hawking of spreading misinformation about threats from aliens, former Canadian defence minister Paul Hellyer claimed recently that extraterrestrials have actually been visiting earth for decades.

Rather than harm mankind, he said, their (aliens') spaceships have provided us information for triggering today's microchip and IT revolution on our planet.

Hawking has recently warned humanity against contacting aliens. According to Hawking, if human beings tried to contact aliens, they could invade us and take away our most important resources.

Hawking has also said that though most extraterrestrial life could be only in the form of small animals, there could also be “nomads, looking to conquer and colonize” other planets.

Hellyer told the Canadian Press that “the reality is that they (aliens) have been visiting earth for decades and probably millennia and have contributed considerably to our knowledge.”

He said our computer screens have their origins in alien spaceships.

Blaming Hawking for scaring mankind about aliens, he said, “He (Hawking) is indulging in some pretty scary talk there that I would have hoped would not come from someone with such an established stature.” — IANS
