How did everything start?And how did we come to exist?In one book Oxford Professor Tim Coulson seeks to simply explain what science tells us about the history of the universe from the Big Bang to the existence of humanity, and whether our existence was always inevitable or if we are just incredibly lucky.Coulson's engaging and accessible storytelling will enthral even the most reluctant of readers with its exploration of what thousands of years of study has told us about who we are, where we came from and what happens next.
