That GMA segment wasn't quite as fundie-centric as the original poster implied.
It dealt as much with humanity's search for meaning in life as it did with whether or not we're "hard-wired" for religion (be it Christianity or any other belief system).
The idea is also not a new one--French anthopologist Rene Girard has written extensively on the almost universal occurrence of this in human society; the best of his books is Violence and the Sacred, (published about 30 years ago, and still in print) and one I highly recommend to both believers and non-believers. It is one of the most fascinating books I've ever read (and I've RE-read this one several times).
Girard details at length the human need to "create" a god or gods (talks about everything from the Greek pantheon to Christianity and beyond), and the purpose that serves in society. He does this not from a pro-religion or anti-religion standpoint, and is careful to point out how certain aspects of this very human tendency can be extremely destructive.
Here's a link to the book on Amazon (complete with a few excerpts):

You can find a few tidbits here:

We humans are interesting critters, and there's something deep within how we tick that leads to a search for meaning.
