The Tree of Knowledge was located in The Garden of Eden. The tree was located in the middle of the garden. When God made Adam and Eve, he put them in The Garden of Eden where he told them they could eat any the fruit from any tree except the tree in the middle of the garden(Tree of Knowledge). One day Eve was tricked by a snake into eating fruit from the Tree of Knowledge. She gave some to Adam too, and as a result the first sin happened. The results of the sin made them relize they were naked, and they quickly gathered "clothing" to cover their privates. Therefore proving the tree had special powers. God later punishes Adam and Eve for their sin.
