An amazingly fascinating and enlightening documentary. To reveal in such detail the evolution of our earth and how we came to be here today is incredible. To think that our human time on this earth has been brief compared to the life that has dominated and become extinct due to Mother Nature. A truely not to miss documentary, one that reveals how fragile life was and still is, and that change is constant. If you want to understand evolution and our earths history from the beginning this is a documentary I highly recommend watching the full 8 episodes. Couldn’t have had a better presenter than Morgan Freeman.
