And I think what science is starting to be able to tell us is some of the likelihoods of some of these events occurring on the grand scale of the entire universe.

We don't have any, the only intelligent life, and in fact, the only life we have found so far is on Earth. However, we have only looked in a very tiny corner of our neighborhood, very small part of the universe for evidence of life coming from elsewhere. So there are trillions and trillions of planets in the bit of the universe we can see, that's called the observable universe.

Yet we've only pointed our telescopes at about 6,000 planets. And the ones that we've pointed the telescopes at tend to be gas giants. So planets a little bit like Jupiter or Saturn that, as far as we can tell, don't have liquid water. And we think that liquid water is necessary for life.

So although we haven't found any evidence of intelligent life elsewhere, we haven't looked very far or very hard at all.

I think it's the latter. And so one of the challenges is we don't know how long intelligent life lives in civilizations where they're capable of sending out signals for other intelligent life to detect and then respond to.

So all of the civilizations that have appeared on Earth before, so the ancient Greeks, the ancient Egyptians, the Aztecs, et cetera, they've only survived for a few hundred, possibly a few thousand years. Our current civilization is a few hundred years old, a couple of thousand tops, and we don't know how long it lasts for.

Now, if you think about it, the universe is 13.8 billion years, so a couple of thousand years is but a blink of an eye. And so the likelihood of two intelligent civilizations being close enough to gather, close enough to one another in the vastness of the universe to communicate, is actually quite a small probability.

But despite that, we are going to keep listening out and we're going to keep listening to see whether there's any evidence of intelligent life. But what we might find is evidence of simpler life, say bacteria, living on other planets.
