In the movie Wonder Woman, we see Wonder Woman as a child who grows into an adult. During the same time we see the people around her - the Amazons - not seem to age at all. It's revealed that Wonder Woman is special.
She's actually a God and presumably immortal
The Amazons are, well, not quite human, but they aren't the same as WW.
It's also revealed that:
A long time ago there was a war between the Gods and all of them perished by the hands of Ares. Before Zeus died, he created Wonder Woman out of clay.
All of the Amazons have bronze aged weaponry and do not seem aware of the changes to the outside world. This suggests that they are several thousand years old.
Presumably Wonder Woman has a normal life span as a child and has just become an adult at the beginning of the film. This seems very incongruent to me. Maybe I missed something though.
So, does the film or the DC Extended Universe give any indication of how old Wonder Woman is? Or is my assumption that she's several thousand years old (based on the weaponry) correct, despite the apparent incongruity I brought up?
