Well it(religion) has been with us for ages and we didn't always have science. And since only recently has science been able to disprove certain religious ideas and now with the internet religions days are seriously numbered.
Even Isaac Newton believed in the God of the bible and he was a very great scientist, but that in the 17th and 18th century. This things take time to ripple thru society until it becomes so well established in their collective knowledge that only a very tiny minority don't understand it. I think this is what will eventually happen.
