In some developed countries the major religions are thriving. Some places seem to be rather churched-out though. This is most predominant in certain areas formerly dominated by the Roman Catholic faith, such as Quebec. The major Protestant church in my city is working to bring religion back to those areas and last I heard has been making quite a bit of headway. I think most folks are still very open to religion, but less open to traditional (preachy and/or unrelatable) ways of presenting it. Everybody needs something to believe in, and while the actual scientific facts can be interpreted to support either theistic or atheistic opinions, the choice to believe that life is without purpose, plan, or meaning, while offering a sense of self-reliance and freedom, brings little comfort in difficult times.
Really, since there's no inarguable proof one way or the other, in the end, it all comes down to personal preference. Faith in a god, or faith in no god. It's still faith. Personally I prefer the logical interpretation of scientific facts that suggests (quite loudly in my opinion) a purpose driven design rather than a random statistical blip. The implications of this, even apart from religious dogma, are very powerful, and very comforting as far as I'm concerned, but that's not why I choose it. I choose it because it makes more sense to me rationally. I think if I found the evidence to point more strongly to the blip, I'd be a very different person, and likely a much less happy and content one.
