There will always be a desire to try to understand the meaning of human existence, even without believing in a supreme being. Maybe some people will be content to conclude that existence has no meaning and will just carry on. But what all these discussions relating to the decline of church attendance seem to show is that a lot of people are turning away from the rigidity and dogma of organized religion but not necessarily always rejecting the concept of - not "god" as defined by a particular religion or denomination - but of some greater spiritual force or reason for existence, or something. Buddhism, for example, is considered a religion, but it's an atheist religion. Buddhists don't believe in a supreme being, but they do believe in spiritual practices intended to lead to personal enlightenment and the overcoming of suffering. Some might look into yoga, various kinds of meditation, even personal syntheses of religious or spiritual beliefs. Everybody has their own ways of looking at things that don't involve attending religious services or accepting specific creeds. I think some versions of personal spirituality will always exist even if the influence of organized religion wanes.
