In November 1909, the First Presidency (Joseph F. Smith, John R. Winder, and Anthon H. Lund) issued an official statement on the origin of man, which included the following: “Adam, the first of all men, was formed from the ‘dust of the ground’ (Genesis 2:7). … All mankind … are born into mortality ‘by water, and blood, and the spirit,’ and so become ‘of dust’ living souls (see Moses 6:59). That is … ‘all who have inhabited the earth since Adam have taken bodies and become souls in like manner’” (in Clark, Messages of the First Presidency, 4:205; italics added).
“We were born of the dust of the earth in the same manner that our first earthly father was born of dust. Our bodies … were formed from the elements of this earth” (McConkie and Millet, Doctrinal Commentary on the Book of Mormon, 2:140).
