They could be from somewhere in the local system and we just haven't found them yet for that matter.
If you want to adopt the Bob Dean "We are in a zoo" concept then things could be constructed in such a manner that prevents us from seeing them normally. They are here but our 3 dimensional consciousness does not perceive them under normal conditions. They watch us from a blind so to speak. How scary to you want to get with it?
