Rameses III recorded his conflict and defeat of the sea peoples at Medinet Habu.
There are drawings in Egyptian hieroglyphics of a victory by Rameses III of the Sea People. So, for the most part we knew they existed. They were not weak people, as a matter of fact there are some musings that the "Goliath" in David and Goliath was a member of this society which when land based were the Philistines.
They were not necessarily learned people as there are no writings or recordings BY them so much as records by others OF THEM.
The Sea People hold testiment to a greater understanding of survival at any stage of the human condition.
It is easy for anthropologists and archeologists to piece together ancient human history through established civilizations, but, far more difficult to actually define 'the people' as 'the masses' that actually lived during those times.
It is very easy to define a people by their documented leadership, but, far more difficult to define a people by their 'human condition' or 'state of play.'
I do not view "The Sea People" or "The Sea of People" as a single record of a human society poorly understood or documented, but, more an understanding of 'the human condition' as has moved history forward in those years, decades, centuries and millenium where 'profound' history lacks.
I do not believe 'The Sea People' were a single phenomena. I believe that is where most human live life. Among each other, sharing strife and coming to common realities.
What is most extraordinary about The Sea People is their existance at all. No profound leader. No notable general. And what seems as though a more 'common democracy' with 'common goals.'
The invasions by The Sea People of Egypt also shows how a mass of people long to improve their human condition. How they come to a 'tipping point' if you will that sets them on a path to 'achieve' regardless of their preceived 'status' or 'understood' inferiority.
Somewhere in the human history at people that have suffered and perhaps paid a price to move history forward. It is not uniquely American to seek these values and goals. They are there as a part of the human condition throughout history.
Invisible.
With only occassional mentions of their power and prowess.
