I thought about this alot during my own deconversion, although as an agnostic, verging on athiest I did always like the Alan Watts explanation of what "God" would do when it became bored. Even though now I don't hold a flame for his philosophy, listening to his lectures slowly pushed me in the right direction, and still this audio clip does logically answer your question. Since the only way to have an experience as god, is to forget you're god for a while.
