Likely the angels and demons are both inspired in part by alien activity. God sometimes has to lay a smack down on reckless aliens that get too exploitative. Particularly aliens who are rationalistic (i.e. godless thinking God is just a more advanced alien) and genetic manipulators (i.e. Nephilim) or who like to take over human minds. (aka possessions)
Some of the official UFO descriptions sound an awful lot like biblical descriptions of angels.
