It's hard to talk about the history of science without mentioning the history of religious people doing everything they could to stop its advancement.
Which proves my point, it was about man's history, not the universe. Many scientists were Christian but he neglected to mention it. Did he mention Georges Lemaitre? His show was for lemmings of weak persuasion to be influenced into a belief. I don't recall Sagan needing to smear any religion to discuss the aspects and facts about the universe.
Most of the scientists he spoke about in the show were religious. Since there was little science back then it made perfect sense to believe a sky pixie did everything. Now it just so happens that most of their discoveries were at odds with the belief of the church to the point of them fearing for their lives. That's why Copernicus did not release his book until he was on his death bed.
The histories of science and religion will always be tied together because science is the practice of testing faith.
Here is a list of scientists discussed on the show:
The Scientists of Cosmos A Spacetime Odyssey Black Geoscientists
What was believed when and where has zip to do with our understanding today. And just because science has more information about the universe does not mean it will have any answers regarding its' beginning. Science can be misused to spread a faith, so the whole premise of the show is weird. It does fit in with his stupid tweets though.
Faith has no bearing on science.
Well, then what is faith?
Faith is believing that all we see around us is a result of helter skelter evolution with no design, no plan, no brain, no mind, justifiable by the passage of time of a few million years.
Faith is the denial of the special relationship between humans and canines, writing it off as evolution. Safe bet that those who subscribe to the theory that this relationship is not of a wise and thoughtful accommodation of both human and canine needs never had a canine friend nor would they ever want to have one.
Faith or should I say leap of faith is the arrogant and know-it-all dismissal of everything that they refuse to comprehend, let alone acknowledge.
Pity them all.
