In Hebrew, Adam means 'human being' and Eve means 'life.' The story is an ancient mythology used as a parable to teach that if you believe in religious dogma that teaches a war between good and evil, or God and devil (fruit of good and bad), then your consciousness is paranoid and you can't appreciate that we live on a planet paradise.
What Adam and Eve do is what human beings do - they aren't a couple but a metaphor for every generation of humankind since most believe in false teaching. while the tree of life (Torah) is available, most don't bother trying to understand it, nor do they care.
