Some notes: (1) The gods don’t love people (or create them). (2) The gods are less than our God in many way: power, character, etc. (and they, too, were created). (3) Mythology is more ahistorical. (4) There is more misogyny in mythology. (5) The gods are personifications, so asking, “Do you believe in Venus” is to an extent like asking, “Do you believe in sex?” etc., and so the question is nonsensical to an extent, too.
