More things I learned from the Movie(Hums)

I first of all saw their technologies, I can't really say it's a technologies, but in the Ancient time it might be a higher technologies, such things like an armor for soilders, they invented and invented it was so beautiful and hard to penetrate the armor, and also armies were really good, like knifes it can't be break, and penetrated by enemies, because it was so hard to break.
Also their ships, their ships were so big, I am still curious how did they make that big ships in the Ancient times, they controled their ships to go with using people they used kind of sticks to waves water and go.
These things are what I have learned through the movie in humanity class.
