The universe is large and we are tiny, without the need for further religious superstructure. One can have so-called spiritual moments without belief in the spirit.
Religions are so subtle, so complicated, so intelligent in many ways that they're not fit to be abandoned to the religious alone; they're for all of us.
It's as though either you accept [religious] doctrine and then you can have all the nice stuff, or you reject the doctrine and you're living in some kind of spiritual wasteland under the guidance of CNN and Walmart.
The secular world is full of holes. We have secularized badly.
We may not agree with what religions are trying to teach us, but we can admire the institutional way in which they're doing it.
