I wanna know. In Wonder Woman it's established that Ares killed all the other gods, so it couldn't have been them updating the Amazons on the outside world, and Ares isn't a possibility. Are there Amazon explorers who traveled to mans world? But that wasn't established. How can Diana know how to speak English, French, German etc and not know what a plane or a automobile is? If there's a priestess on Themyscira, or some all knowing Amazon, then where's she getting the information?; again all the gods except Ares are dead.
