At the start of Wonder Woman, we see Diana's "mother", Hippolyta, tell Diana that she was made out of clay and given life by Zeus. This is repeated by Diana at least once.
We later learn;
That Diana herself, rather than the sword she wields, is the Godkiller, the weapon designed to defeat Ares. At this point, she starts calling Ares her brother.
Because of this, I began to assume that Hippolyta had lied, and that Zeus was actually her natural father and Hippolyta her natural mother. However, as a friend pointed out later, the film never explicitly confirms this - the "twist" still works if she's still made from clay, which was the origin of Diana in the comics for a very long time.
Is there any evidence in the film itself, or any statement been made from the people who worked on Wonder Woman, that definitely answers the question of "Is Diana Prince the natural born daughter of Zeus and Hippolyta, or was she really made from clay and bought to life"?
