Q: How long did Adam and Eve live in the Garden?
A: There is no way of telling. The Bible doesn’t really give us any conclusive clues. It could have been a few days or weeks or maybe even a hundred years or so—no way of knowing.
However it does say that Adam got rather lonely before Eve came along so it could have been way longer than many of us think. Also, it could have taken quite a long time for him to name all of the animals and birds (Gen. 2:19).
