The Chance Events That Led To Human Existence

Brian CoxHow have we ended up as the most advanced species on a small blue-green planet, orbiting a seemingly insignificant star, in one of the hundred billion galaxies in the Universe?

Science has found some extraordinary answers to this question. Looking back through time, it appears that our existence depends on an apparently unlikely sequence of cosmic moments.” (BBC)

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!
