None of the aliens / angels 'played' gods. They were gods...as per the definition of their heavenly status compared to incarnated humans ! When they talked to chosen humans, only the latter were authors of their writings, NOT those aliens / angels. Besides, the simple fact that some of them PHYSICALLY appeared on earth, most of them being angels of God, doesn't mean they are fallen at all. It means that they chose to lower their 'frequency', using the properties of the fractal time, to better prove their existence and reach the human consciousness.
