Here is the thing though.  1) we don't know for certain any of those things really exist.  We don't.  We know just one thing that the UFOs exist and that there is strong evidence for 'mind parasites' ('archons' djinn, ... which i personally suggest is an advanced AI in the future that is altering things in teh past in realtime) 2) it wouldn't matter if there is a hierarchy, because if we cut off the ENTIRE level connecting to them, as in eliminate every single person there that they connect to, it would FORCE THEM to make a new connection.  If we were to immunize the whole world against undue influence, and/or watch everyone all at once, then cut that connection, teh no matter how powerful, their power would be completely gone in this world as they would not be able to make a NEW connection This would then force them to leave OR they would finally be forced to show themselves directly, in which case, suddenly we'd know they EXIST "Dark to Light" so to speak.   drag them out into the light, point at them, define them. In order to defeat the enemy, you have to be aware that the enemy even exists, then you have to know who the enemy is, and then you have to know what it wants and how it works
