It's All Happened Before But Will It Again?

It seems only apropos that following my "The Day Of The End Of The World" post day-before-yesterday that I share this short clip as a sort of coda. These two series segments form a sort of bookend pair as they show opposite ends of the story arc for the acclaimed television series Battlestar Galactica as found at the start of the story in the other posting and then here at the conclusion of the episode "Daybreak ~ Part 3", final episode of Season Four and of the entire series. Not only does this cleverly wrap up the series and connect it to present-day Earth but also cleverly gets into some more transcendent stuff such as the nature of human civilizations to destroy themselves and the degree to which there is Free Will and/or it is all essentially predetermined by human predisposition.
