Against being 'in' the world

It doesn't seem right to say we are beings 'in' the world, as if the world were a container within which we exist as a component or resident — as if we are in the world as we are in a house or room. The implication is that the world/room is something pregiven around us that we are not so much a part of than a part within, and that that world/room would continue in the same way if we were not there. It seems better to say we are beings 'as' the world, and that that world is a condition of our being there, as much 'in' us as we are in it.
