Moses 2

 Even though the creation was overseen by Jehovah or the Savior, it appears that when it came to placing man on the earth, God, the Father was firsthand involved where we read - 

"...I, God, said unto mine Only Begotten, which was with me from the beginning: Let us make man in our image, after our likeness; and it was so...."  (Moses 2:26)

It also seems to me that the Lord referred to both Adam and Eve as man saying - 

"...I, God, created man in mine own image, in the image of mine Only Begotten created I him; male and female created I them."  (Moses 2:27)

Thus the word mankind would refer to both men and women.
