I tried to watch the show Cosmos but he screwed it up with a bunch of anti-Christian crap. It was nothing like Sagan's show. He should have just had a different show for religious studies.
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:
