Adam was the first 'angelic' looking being, for he was created in the image of the LORD, which is that of a man, and the Likeness of the Lord, which is Light (see GEN1:26-28;Ez1:26-28; 1Jn1:5): and Eve was the second, who is the Mother of ALL LIVING and is elevated above the 'angels' because she is their mother (1Cor). Therefore, all born of them and their children before they 'fell' (sinned) are the host of angels; and all born after the Fall are the sons and daughters of man.
Realize that Adam is the Devil, and the Serpent (not a snake), and Satan, and others in scripture, because he is the first liar (Jn8:44), since he deceived Eve from the very Beginning by telling her a perverted commandment, one which he added to, and diminished from, and being the very one she regurgitated back to him (the serpent- Gen3:2-3) on the day she first ate the 'forbidden' fruit. Therefore, Adam is the father of both the good angels (the cherubim) and the bad angels (the seraphim), and also all mortals, being those born in sin: and Eve is their Mother.
