Where does wheat and corn originate? First Book Of Adam And Eve. Chapter LXV1

6 Then Adam and Eve again stood outside the cave, and besought God to show them some food wherewith to nourish their bodies 7 Then the Word of God came and said unto him, "O Adam, go down to the westward of the cave, as far as a land of dark soil, and there thou shalt find food" 8 And Adam hearkened unto the Word of God, took Eve, and went down to a land of dark soil, and found there wheat growing, in the ear and ripe, and figs to eat; and Adam rejoiced over it 9 Then the Word of God came again to Adam, and said unto him, "Take of this wheat and make thee bread of it, to nourish thy body withal" And God gave Adam's heart wisdom, to work out the corn until it became bread 10 Adam accomplished all that, until he grew very faint and weary. He then returned to the cave; rejoicing at what he had learned of what is done with wheat, until it is made into bread for one's use.
