It is the people.

The 168 individuals buried in the Windover pond were a community.

They had relationships with each other.

They raised the children who were buried with necklaces and toys.

They cared for the young man who could not walk.

They wove the fabric that wrapped the dead.

They made the bone tools and the shell ornaments and the antler implements.

They harvested the berries and the fish and the game that sustained them.
