Why Are We Here? In episode two, Professor Brian Cox is off to India, where he assesses arguably the first evidence of rational thought in literature - the poetry of the Vedic monks. They pondered mankind's origins, realising there must have been a day with no yesterday - a day of creation - prompting the age-old question of where did the universe come from? Brian marvels that we live in a universe that seems to follow rules - the laws of physics. Rules that have allowed us to consider space on the grandest scale, travelling to the most distant, farthest reaches of the cosmos just by using our minds. Brian also visits Japan, and offers viewers the idea that we live in just one of an infinite number of universes that are being made all the time
