      Billions of years ago, icebergs, which we now call as comets, were believed to have fallen here on Earth and became the seed from which life sprung on our planet. These icebergs were rich in compounds that blended well in the Earth’s environment, thus settin forth the growth of life. These same icebergs were also believed with be what has caused the extinction of dinosaurs over 65 million years ago.

      The comet’s impact bore evidence when scientists studied the Cretaceous Period, which followed the great annihilation. When the comets showered the Earth, scientists say that the atmosphere grew dark for months, changing the course of the environment from which the human beings evolved.

      Comets constantly travel through our space.Scientists say that comets do cross the earth’s atmosphere from time to time, but dissolves before reaching any surface. It’s a natural occurence that if and when it does hit the earth, it can cause catastrophic events worse than earthquakes, tornadoes or volcanic erruptions.

      This documentary, as narrated by William Shatner, touches on the origin, composition and nature of the comets to unravel its mystery and learn about its effects on our own planet.

      William Shatner narrates the documentary “The Story of Comets”.

    • It makes ya think of how easy it is for life to be extinguished in a flash. Its not just asteroid capable of destroying life but comets as well and this increases the odds alot. But overall a well presented documentary.
