Cool down! It was only a supposition! One of several plausible explanations that could be reasonably advanced without resorting to divine intervention!
Your own statement that your daughter had previously believed in "multiple gods" (a "ditzy" belief if there ever was one!) suggests that she is member of the "Bizarre Belief of the Month Club."
Next month, she'll probably be putting her faith in crystals, or astrology, or reincarnation, or some other nonsense.
I would hardly call someone who "flips" on a dime from believing in a whole pantheon of gods to just one "stable."
