“You continue: “If Adam is the ‘leader’ of Eve, it makes perfect sense that he is the one spoken to by God in those circumstances.””

Perhaps, a bit of logic might help here. God does not always speak only to leaders. God speaks to whomsoever He chooses. And sometimes makes leaders of the insignificant ones of humanity. Just because God chose to speak to someone does not mean that one is or even will be a leader – ever.

Further, God did speak to the woman. To assume God didn’t speak to the woman paints a picture of meanness and special preferring between only two. How could God walk among them and never talk to the woman. And we know that God spoke to the woman because she says so.
