Brian Cox, right at the end, looking for all the world like the idea's just occurred to him:

We are the cosmos made conscious. Life is the means by which the universe understands itself.

Carl Sagan:

The surface of the Earth is the shore of the cosmic ocean. On this shore, we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return, and we can, because the cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself.

Ending there with probably his most famous quote. Here he is saying it in vocoder form. Just cos you're a professor on telly doesn't mean you're allowed to plagiarise.

(p.s. "amm" is what we used to say as kids where I grew up if we saw someone else doing something we deemed naughty. Kids do that a lot but the word seems to vary from place to place.)
