Very interesting and exciting showing the exponential evolution of the human race.  If you watch nothing else from the video, check out the segment starting at 8:39 (http://youtu.be/yNLdblFQqsw?t=8m39s).  This shows the history of the Earth progressing 1,000 years every second.  Our thin little slice is just a flash at the end.  Don’t blink.
