I would say that is more a case of the Church meddling rather than religion. The thing is, a purely scientific society would, by now, be practising cloning, humans, genetic manipulation, would be using animals and 'defective' humans for experiments, would probably encourage Euthenasia and Abortion for population control etc. Because that would be, from a purely logical point of view sensible for the human race.
However, the Human Race is not a group of opinionless, emotionless automatons, they have feelings and wants and needs. In a way, religion tries to act as our conscience to sciences' logic. It doesn't work very well at the moment, because of both lack of trust and powermongering, but that, I think, is the way things ought to be.
