Earth may be “the only place” in the universe with life forms intelligent enough to form a civilization, said Professor Brian Cox.

While microbial life forms could well be widespread, the physicist believes that “things like us could be extremely rare”.

Asked about US Congressman Andre Carson’s comments earlier this week that UFOs were “a potential national security threat” that were “real” and “needed to be investigated,” Prof Cox said it was “one of the great mysteries.” ‘ whether intelligent extraterrestrial life forms had found their way to earth.

He told BBC One on Sunday morning: “If you were to force me to guess, I’d say microbes could be anywhere, so we’re looking for life on Mars for example, but in terms of intelligence there’s a thing To Over pondering the origin of life on earth, it looks like we have good evidence, give or take, that life existed 3.8 billion years ago and the first civilization to appear on earth was about now.

“So it took almost four billion years to go from the origin of life on Earth to a civilization.

“That’s a third of the age of the universe, and that’s a long time, which might indicate that microbes are widespread, but things like us are extremely rare.”

Prof Cox added that he believes the greatest risk to humanity’s future is a “lack of perspective”.

He said: “I mean, when we started talking, the idea that we could be the only civilization, for thousands or even millions of light years, I think science is useful on many levels, but one of the things is very useful that gives us a perspective which is a broader perspective and actually i don’t think a lot of us think – a lot of our political leaders maybe don’t really think about it is it possible that this is the only one let’s say the only significant island in a galaxy with 400 billion suns. That counts.

“I don’t think it’s any weird idea. It might focus the mind.”
