I am old enough to have watched the original Carl Sagan Cosmos series. And I still found nothing compelling about his statements and explanations about science and naturalism. And in other occasions when I have seen Tyson under a full head of steam I found him to be a rather narcissistic blowhard -- but that is, of course, an ad hominem and takes nothing away from the truth or falsehood of the information he presents. I will do my best to make time to watch an episode or two, but while I do, consider this:
Scientific fact is not determined by consensus. The phrase "most scientists believe" is usually a prefix to a statement that someone wants to have weight, but for which there is no definitive proof. If "most scientists believe" that there is no deity, that is not, in and of itself, proof that it is true. Science, as Octavia_Melody has well and reasonably stated, is the study of the natural, and can make no pronouncements about the existence or actions of the supernatural. On the question of origins, all science can do is take what they observe happening in the present, and project in time, "running the film backwards", using logic and data. And there is nothing wrong with that, as a means of coming up with a theory. Some things, though, cannot be explained by current science. Some may, in the future, become evident as science advances. But some can never be explained except by breaking through the limitations of what we can observe -- multiple universes, "branes", and stable singularities which inexplicably came into being and even more inexplicably became unstable and exploded.
None of this can be proven, it is just an example of how far a mind will go to avoid the existence of something that not only cannot be explained in scientific terms, but might actually want something of us. The one thing we must do away with at all costs, is the idea of personal accountability.
