This video comes from a few years back. As far as I can make it, Bill O'Reilly had as a guest on his "Fox News" show a Godless Atheist, and at some point during the segment (or perhaps it was the whole segment) they were discussing the relationship between science and God. What I gather from what's said on this video is that Mr. O'Reilly's must have been suggesting that because science can't explain something, that ipso fact must prove the existence of God.
(Except for very far right, radical conservatives, I've never quite understood why for so many other mere "far right conservatives" it's so difficult to accept the validity of science. If one finds it a threat to your belief, just look at it from the perspective that God created scientists, and so everything they do and say is His will. Then, if they're explaining something that you think contradicts God, you know they're only saying it because God wants them to, Which is further proof of how mysterious are the ways of God...)
But I digress. (Or deGrasse...)
Anyway, here is a small part of a much longer interview, when Neil deGrasse Tyson is asked about the segment from Bill O'Reilly. I suspect that to those on the far radical right, Mr. Tyson is another of those Godless Atheist Heathens. Though he's never trying to disprove the existence of God, merely trying to expand our own understanding of the world we actually live in and, as he notes eloquently, trying to show a curiosity about it.
