Suave, perhaps you're misinterpreting the data from the experiments.
The experiments with TLE suggest there is neurological reason why religion has been a huge influence throughout human history. It proves there is a "God center" of the brain. No one would attempt to explain why that part of the brain exists.
It would be just as abnormal to be a true atheist as to have have overactive religious delusions, as being a true atheist shows that portion of the brain (responsible for some of the most primitive brain functions) is not functioning as it does in most humans.
Pointing only to the overactive "God center" and ignoring the inactive "God center" suggests preconceptions of the value of religion.
As I've stated in an earlier post, the way the data was used in the text you quoted, is junk science. The data only proves there is such a center in the brain, and in no way suggests its value or that some pill should be created to fix it. There is an assumption in the text that less is better, but that is not suggested by the data. Hence it deviates from science and is basicaly, crap.
