Even a kid in kindergarden can ascertain that the verse simply implies that is what God told Adam and Eve. By jolly, do you think the Bible is going to describe every detail...(i.e. Adam and Eve visited the south pole...they built a house, they named their favorite pet Lion 'Leo').
The expectations I would have for the Bible depend on what you expect me to believe the Bible
is.
As a written record of traditional Hebrew oral myths? No, I wouldn't expect the Bible to go into every detail, nor provide any more information than is necessary for the reader to get the general gist of the myth.
As God's inerrant Word to His creation, detailing every way in which a person should live? I would expect significantly
more detail, and at the same time,
less outright self-contradiction.
Like I said it all depends on what you think the Bible is. It's certainly what we would expect if it's just (heh; "just") a long-surviving record of the myths of an interesting culture. It doesn't even
begin to rise to the level of a supernatural dictation from the Creator of All. Don't discredit
your intelligence and try to assert that you or anybody couldn't write, on their own, a more insightful and self-consistent bible.
