1) Polycarp and Ignatius can only have been taught by John if you place *that* John (it's not clear which one they are even talking about btw) around 90ad, and not around 70ad, as I do (given the timeline that actually makes sense with Jesus imminent return at that time; in that generation).
2) Both the sons of God and this satan are human here. Nothing in the Hebrew makes it spiritual. The same phrasing is used for (god-serving) humans several times.
3) In Luke 10 Jesus is employing a literary device when he says he saw the enemy fall from the sky like lightning. The verb “see” is theoreo which means to perceive, to discern, to view mentally, to see as in a vision. Similarto the imagery John gives us in his vision he “saw”. So Jesus had a vision of the enemies of God falling from their high position, the heavens or sky, and were brought down to earth or made low. “Heavens and Earth” was an idiomatic Greek expression used to describe those in power religiously and politically (the heavens) and the common people they ruled over (the earth). So many of these Hebrew idiomatic expressions have been improperly translated, either in ignorance or intentionally.
4) It does not clearly have three characters. If it would than the serpent it somehow just magically disappearing and shwoing up all the time. Also (angel of) God never adresses that suppsosed third character. Also, how would that character even know what God told Adam? Was he magically there too?
Saying Satan is a real evil entity is giving him powers equal to Gods, while also moving us into victimhood instead of self-responsibility over **our own** sin. There's no Satan/Lucifer/Azazel/... with his army of fallen angels and demons attacking you 24/7, knowing everything about everyone.
5) I believe we have what we need in the Bible.
