In this clip we explore the existence of extra-terrestirial life and the biggest threat to humankind.

As Carl Sagan said "if we are alone in the universe it's an awful waste of space".

"The biggest threat to us is human stupidity"....

How cool it is two talkative presenters remained silent, continued watching and listening to Brian, shows when you talk science no one can stop you talking

[thedustiev]

This guy always lights up when he talks, could watch him all day

[hanstubben]

Brian Cox is so down to earth with simple observations, and can express in simple language what really matters!

This man is rapidly becoming something of a national treasure.

Brian are so smart, clever, down to earth, polite and wellspoken even for a swede like me. And he also seem so friendly, a person one could listen to for a very long time

"Never underestimate the power of human stupidity"

Brian Cox is exceptional because above all else in these types of conversations, he's good faith. He may personally not think there's any credence to the different stories, but he's certainly open to the possibilities, and to talking about them. You can't ask for more from someone in the conversation really.

I absolutely love Brian, he’s a treasure amongst humans and the irony is he’s most scared of us. Let that sink in.

[davidfoley]

Mr Brian Cox speaks the amount of sense everyone should listen to.

[Ukie]

The biggest threat is human stupidity….well said.
