Brian Cox tackles the question that unites the 7 billion people on Earth, why are we here?

Brian reveals how the wonderful complexity of nature and human life is simply the consequence of chance events constrained by the laws of physics that govern our universe. But this leads him to a deeper question - why does our universe seem to have been set up with just the right rules to create us? In a dizzying conclusion Brian unpicks this question, revealing the very latest understanding of how the universe came to be this way, and in doing so offers a radical new answer to why we are here.
