The documentary is very scientific considering as many options/possibilities as possible. Everything is well done. Just when you think they will skip an idea or just touch one it, they do a good job elaborating on it. The topics covered include: How the Earth formed?, How common is an earth-like planet?, search for extra-solar planets, the chemistry of life, formation of life molecules, big bang theory, cosmic microwave background and much more. If you like documentaries about origins of life and space, then this is likely one that you will enjoy.
I would strongly urge all members of “Planet Earth” to take a few entertaining and informative hours to understand what we know today about the origin of the Earth. Even if you are not in agreement, it gives you an idea on what popular consensis in the scientific community today.
