All the worlds most popular religions argue that god is all of the following though.
Maybe now, but the ancient Greeks certainly didn't think that any of their gods were all-loving (capricious pricks who humans were better off not attracting the attention of), all powerful, or especially all knowing.
Greek, Norse, Babylonian, Egyptian, etc pantheons all viewed the gods something akin to what people in the DC or Marvel universe would view superheroes as: people with strange unnatural powers far exceeding theirs who were basically people otherwise...and it's usually better not to come to their attention.
