These EBE's are here to save mankind from themselve's and restore planet Earth, where all of mankind will live in peace. These aliens are completely benevolent towards humans and only wish the best for us. I believe the term "New World Order" would fit nicely into this scenario. These EBE's are here to observe mankind only as they have for thousands of years. They may at rare occasions push us in the right direction when we have gone astray but overall they leave us to our own devices and simply observe.
