Asserting that there is some being you have no evidence for is always silly, no matter what veil you try to throw over it (in this case, naturalism). Could there be some super smart, cosmic, Cthulu-esque entity that we might consider a god? I mean sure... there could be. But why even assume that? Even that comes down to faith.
If you're frightened of dying, and you're holding on, you'll see devils tearing your life away. But if you've made your peace, then the devils are really angels, freeing you from the Earth.
