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)
