In simpler terms, it makes no sense for a temple to encourage people to settle in one place and develop agriculture or housing, when they would already have needed to settle in that place in order to think building a stone temple was a good idea. Sure, once the settlers built their temple, people might have come from all around to see and worship at it, and some may have even settled with the original settlers. But there would have needed to be people who had roofs over their heads and crops to eat living there before the temple could be built.
tl;dr Stability begets civilisation, not religion. (Organised) religion and civilisation are caused by stability, not by each other.
EDIT: Having actually read the article I don't think this really changes anything. Religion has always been around and would always have had a place in a hunter-gatherer society for whom, often, good and bad results are based mostly on luck and guesswork. Having something to believe in when your entire family's wellbeing hangs in the balance would be somewhat reassuring. Building a temple to make offerings to those gods/forces/nature would only make sense -- and the more effort you put in (the more you 'offer' in its construction), the more devoted it shows you are, thus they will like you (assuming spiritual forces have human reasoning, an assumption many people have perpetuated even to this very day).
Basically the guy's a crockpot who probably doesn't talk to people very often and makes wild assumptions that ignore human nature. Happens sometimes.
