How did Zeus become Aphrodite's father?

Answer 1

One myth claims that Zeus had Aphrodite with Dione, the most common myth however is that she rose fully formed out of the sea after the god Ouranos's (Uranus) genital were throw into the sea, hence her name which means 'sea foam'.

Answer 2

Zeus did not become Aphrodite's father. In Greek mythology, Aphrodite is said to have been born from the sea foam that formed when the severed genitals of the Titan Uranus fell into the ocean. She is typically regarded as born from the sea and does not have a mortal or divine father in most versions of her origin myth.
