One of the basic purposes of traditional religion has been to provide us with a sense of meaning and purpose. You're asking me a very particular personal question. This tells us something about how the mind works. It doesn't necessarily serve as a means of figuring out which belief cuts the deepest. That's the easy way.
Humanists recognize that there's another way.
It's harder and it's not undergirded by a long history of sacralization. And it may never have sacred prayers and sacred hymns. But it will instead provide a substitute, based upon an understanding of how the world works, that in time could grow stronger than the support and psychological strengths provided by traditional religions. One thing that is apparent now is that most religious mythologies are poor descriptions of how the world works. So in effect they are fallacious.
