I’m not even going to list the show’s executive producers, directors, narrators, or cast of this show.  Not when the show has run since 1974, but I did list key people for this episode. Time is limited and so is mine right now, but this episode was fascinating and interesting to watch.  If it weren’t for the asteroid hitting Earth millions of years ago, killing nice and mean dinosaurs as we saw in Jurassic Park, humans probably wouldn’t have existed.  Do you really see dinosaurs and humans co-existing?  I don’t no matter how much it would be cool to see one alive.  The bulk of this episode shows various scientists removing and analyzing rock from the Chicxulub crater for greater understanding of the asteroid and its impact.  The destruction of it was due to its power and speed.  It had the energy force of 10 billion atomic bombs and speed of 40,000 mph.  The dinosaurs not killed on impact suffered a longer death by the release of sulfates and blockage of the sun, which eventually led to starvation.  So what are the chances of an asteroid hitting Earth again? According to a team from Princeton, the odds are in our favor.  There is a 1 in 5,000 chance of an asteroid big enough to wipe out civilization in the next 100 years (stated in 2011).  If asteroids regularly hit planets including Earth every 100 million years, I’d say it’s safe to say the Earth isn’t disappearing anytime soon, but the fact human beings live for such as short amount of time still scares and fascinates me.  After you watch this episode from 2017, there are 879 episodes to choose and a few are on Netflix.

I rate NOVA episodes PERFECT at 100%.
