1. As soon as creationists use actual facts: objectively observable, testable and debatable facts instead of simply pointing at a book and saying "there's the proof" then I will be more than happy to bankroll a Cosmos style show just for them. I don't have the money but I don't think they'll ever have the "goods" so I don't have to worry about raising it either. "WE" the collective have debated the creationist/evolution ideas ad-nauseam and creationists have no new information to bring to the debate. All of their arguments have been debunked and science has provided provable or plausible answers to every question posed to it.
2. Your right to free speech is just that a right. No-one has any obligation to provide time, space or audience for your expression. If you want to produce a show about creationism and can get a network to show it, good for you. Some believe we are all defended from aliens, or a flying spagettin monster; Cosmos has no obligation to offer those opinions either. Look Christians: There are about a billion of you. There are also about a billion Muslims and a billion Hindus and all of you believe that you worship the one true god and know the true meaning of all the ancient texts. You can't all be correct and the most plausible answer is that you are all wrong and there is no god, gods, spirits, or any other super natural powers.
3. The premise of most of religion's dislike of the Big Bang theory is that "nothing can just be, it has to be created". Well, where did you god come from if nothing "just is"? How improbable is it that super intelligent being that exists everywhere all the time(omnipresent) and has total knowledge(omniscient) and control(omnipotent) over every single quark in the entire Universe just spawned in to existence out of nothingness? For all your rants, you have the same problem as science except that science says "we don't know but we're looking really hard". Religion says "your question is stupid" (see item #1).
