Consciousness of a real and meaningful world

is intimately connected with the discovery of the sacred. Through experience of the sacred, the human mind has perceived the difference between what reveals itself as being real, powerful, rich, and meaningful and what lacks these qualities, that is, the chaotic and dangerous flux of things, their fortuitous and senseless appearances and disappearances. . . . In short, the " sacred" is an element in the structure of consciousness and not a stage in the history of consciousness. On the most archaic levels of culture, living, considered as being human, is in itself a religious act, for food-getting, sexual life, and work have a sacramental value. In other words, to be—or, rather, to become—a man signifies being "religious."

—Mircea Eliade, A History of Religious Ideas

Whether God "exists"

or not is a triviality.

What matters is what kind of life and what kind of culture issue from faith and from faithlessness. Modernity supplies the answer. Without God as center, life and culture degenerate. Neurosis and madness proliferate. Freud did not sufficiently appreciate what he himself observed, that religion protects against neurosis. Like all moderns, he could not abide "illusions" and this blinded him to the fact that "fictions" and "illusions" are the stuff out of which culture is spun and are needed to protect human beings from the sterilizing effect of consciousness. 

Consciousness has to produce something that protects against its own death-dealing radiation. That is what produced religion.
