Jesus Christ is the Only Begotten Son of God:

Jesus Christ is the firstborn spirit child of God1 and although each of us is a spirit son or daughter of God, the Eternal Father, only Jesus Christ is God's son in the flesh. Born of the virgin Mary, Jesus Christ, is the only begotten son of the Father.2

The Only Begotten is just one of the many names of Jesus Christ, who is also known as Alpha and Omega, the First and the Last, and the Creator of All Things.

Christ is the Creator:

Under the direction of our Father in Heaven, Jesus Christ created the earth and all things that are upon it, including the plants, animals, and mankind. He also created the heavens, thus He is the creator of both heaven and earth.

"Behold, I am Jesus Christ the Son of God. I created the heavens and the earth, and all things that in them are. I was with the Father from the beginning. I am in the Father, and the Father in me; and in me hath the Father glorified his name" (3 Nephi 9:15).
