Hey, it's already been shown in the US.First Life is a 2010 British nature documentary written and presented by David Attenborough, also known by the expanded titles David Attenborough's First Life (UK) and First Life with David Attenborough (USA). It was first broadcast in the USA as a two-hour special on the Discovery Channel on 24 October 2010. The British version is a two-part series, beginning on BBC Two on 5 November 2010.
First Life sees Attenborough tackle the subject of the origin of life on Earth. He investigates the evidence from the earliest fossils, which suggest that complex animals first appeared in the oceans around 500 million years ago, an event known as the Cambrian Explosion. Trace fossils of multicellular organisms from an even earlier period, the Ediacaran biota, are also examined. The naturalist travels to Canada, Morocco and Australia, using some of the latest fossil discoveries and their nearest equivalents amongst living species to reveal what life may have been like at that time. The series utilises cutting-edge visual effects to reconstruct and animate the extinct life forms.

Which is good in a way, because ...

Interestingly, although Attenborough's documentaries have attained immense popularity in the United States, several have never been made available on DVD in NTSC format, most notably those that cast doubt upon conservative religious or political positions. These include:
* Life on Earth, which examines the evidence for evolution.
* State of the Planet
* The Truth About Climate Change
