the egyptians advanced our knowledge in architecture, engineering, sea travel, agriculture, irrigation, mathematics, metal working and gilting, masonry, building in general, and the written word to name but a few. It is also emerging that the so called slaves who built the pyramids were more likely to be willing farmers looking for an income in their off season. I am not saying there was no slavery. Also of course some advances have been made without a view to conflict but most have been refined by war. Ships used the steam engine for example. Look at civilisations who long ago abandoned war. They are technologically stunted. Not saying this is a bad thing.
