I agree with most of the atheist views of the issues, but I have to disagree when he claims that "we have seen no signs of supernatural events occurring": In my view, I can see at least three very "supernatural" (i.e., physically/logically impossible), all very much part of the current "concordance cosmology model" (goo.gl/SDRaKB), which quite a few modern precision cosmologists actually believe is "physical truth":
1) "Creation" of all energy/mass there is, out of nothing, a long long time ago. Like thirteen thousand eight hundred million years ago. This smacks of "divine intervention" (i.e., "let there be light!").
2) Hyperluminal expansion of this something ("inflation") which had a rate of expansion exceeding lightspeed by a factor of 10^25 (that's a 1 followed by 25 zeroes). We're talking massive momentum, here!
3) Space itself is said to be "expanding," and thereby relocating/displacing enormously massive objects, like whole galaxies, without actually moving anything. This is a good one: distances between galaxies increase, but galaxies are not moving (much). Yeah, right!
All three pretty Neat Tricks (clearly and distinctly super*natural)! No. I do *not argue that the alternative is divine intervention by some "Good Ol' Designer," not at all. But I do believe there is a possibility that the Universe always was, and that all energy/mass therein is constantly and eternally being "recycled"... Somehow.
Oh well, we all believe in something... I believe I'll have another cold beer!
Formation <sic!> of something from nothing: Supernatural (if not impossible)
Hyperluminal "inflation": Supernatural (if not impossible)
"Expanding Space" displacing massive objects at high speeds, with no movement or force involved: Supernatural (if not impossible)
And, to repeat: I am (or was) in no way invoking "the god of the gap" as you said. On the contrary, I am (and was) suggesting that we keep searching for an alternate, and more scientific explanation for the Universe origin. No "god" involved.
And F.Y.I., I am not the one claiming supernatural origins -- the BBT faithful are!
