tenyearsafter....Your question is precisely the kind that inspired midrash over the millennia. The original narrative in Genesis is laconic and has very little exploration of the characters' thoughts and feelings; the first hint of any interior characterization is only in 2:25 ("they felt no shame"). But the story does have enough elements for an interpreter to work with, whether by filling in the gaps with imagination (as is common in midrash) or by making exegetical inferences from the narrative presentation. Ha-'adam (the man) and Ha-'ishah (the woman) before their "eyes are opened" are both naive and display childish innocence (easily influenced, feeling no shame in nakedness, have their needs provided for by Yahweh Elohim, etc.), and they have no life experience to rely on. Yahweh Elohim gives the command to Ha-'adam in much the same way that a parent tells a child to not touch a stove (for in the moment you touch it, it would burn you). The man's understanding of the command is nowhere related, but in light of the theme of childish innocence, it is possible that he and Ha-'ishah are pictured as having an immature understanding of life/death. This is especially heightened in the contrast between them and the 'arum (shrewd) serpent who, by virtue of being a serpent, knows all about life and death (as serpents rejuvenate themselves by shedding their skin and thus were commonly thought in the ANE to be extraordinarily long-lived). So Ha-'ishah tacitly accepts the serpent's understanding of the lethality of the tree of knowledge of good and evil as her own by partaking of the fruit, setting aside her prior understanding of the divine command (which, incidentally, she distorts in several key ways). Only subsequently, after gaining a more adult knowledge of shame, female subordination, sexual desire, and painful childbirth (see 3:10-20) does Ha-'ishah discover the truth about life and become Hawwah (Eve), the life-giving mother of "all living"; the name puns on the Hebrew word for "life" but etymologically it is derived from the word for "serpent". As for Ha-'adam, he keeps his name because "dust you are and dust you shall return" (= 'adamah "soil, ground"); in other words, while Ha-'ishah's new name emphasizes her new understanding of life, Ha-'adam's name is revealed to him as pointing to his eventual death.
