Might "The others" just detatchedly observe us? Possibly, but if so, why should we assume we might be able to detect their presence, if their intent were to be that they remain unknown to us? As long as we're playing with assumptions, it would be reasonable to assume any technology sophisticated enough to get here from some other civilization from somewhere out there in the stars would be equal to the task of remaining hidden to us if that is what "They" wished to do. Equally, perhaps even more, reasonable to assume, would be that a starfaring civilizations' encounter with another civiliation in the vastness of space might be cause for considerable fanfare and eagerness to meet and get to know the new neighbors.
I think a sophisticated race, which is able to voyage to other solar systems deals with us like we do with depauperate species.
For example, rats in a lab dont know what the scientist plan. They never have the chance to find out what are their intentions. Most of them, even don't know that there are men and women in white mantles.
If there is an alien race examining us, it would be fairly similar. Of course they wouldn't appear in a large city like NY and proudly present, that they are here, so a study of our behaviour would be impossible.
But they wouldn't be concerned with hiding themselves at any price.
