Interesting program. First time I've heard it.
During your conversation with Dr. Livio you said, "You can say that our minds give rise to mathematics, but then mathematics are found to explain the physical world, which is a very mysterious thing to think about."
I do not think it is at all mysterious that concepts humans develop explain the natural world. The human brain is a product (both materially and developmentally) of that world. Therefore, it is not surprising that people discover (and I think "discover" is the appropriate word) relationships that exist in, fit, describe and explain that world. How could it be otherwise? Things that develop in the same universe *must* fit, otherwise they could not exist the same universe. "As the twig is bent, so grows the tree."
Listening to you talk I get the impression that you are so attracted to and captivated with the feeling of "mystery" that you would prefer to maintain the mysteriousness about something rather than find an explanation that would dispel that feeling.
You asked if there is something revealing in the fact that even non-religious scientists use the word "God" when trying to explain things they cannot yet explain. While I am not a scientist, I suspect that non-religious scientists use the word "God" because the concept of a creator is so ingrained into our culture and our heads that it's difficult not to use, and for lack of a better or more succinct way of saying, "Whoever or whatever created the universe..." or "However the universe developed..." Using the word "God" is also more "catchy". "Is God a Mathematician?" is certainly more marketable than say, "Did The Universe Develop According To Laws That Can Be Described Mathematically?"
Personally, I am inconsistent about a belief in God. Objectively, I do not believe there is a supernatural being. On the other hand, when I have something difficult to cope with I catch myself unconsciously hoping God will intervene somehow. It's like a form of hope that things will turn out fair and right.
I liked Dirk Felleman's comments about mysteries.
