We Are Here: The Pale Blue Dot - Carl Sagan (please watch video)

I find this video very interesting and beautiful, and wanted to share. (Actually, I initially shared it with a friend. She suggested that I share it in a post, and I liked the idea.) It's part of a video, narrated by Carl Sagan, where he reflects about a picture that shows our Earth as a pale blue dot in space. So, please watch it and maybe let me know what you think.
