So begins a fascinating journey through time, detailing the chance events that led to human existence. It’s all part of Brian Cox‘s Human Universe show, which is currently airing on TV. The trip takes us from today all the way back to the beginning of the universe, 13.8 billion years ago. During that time, changes in the Earth’s orbit, chance asteroid strikes, the evolution of cyanobacteria, “The Fateful Encounter”, the combination of complex molecules, the arrival of water, the formation of the moon and our Sun, and the Big Bang all occurred, leading to us.
It’s rather amazing we’re here at all. Onwards!
