How do Latter Day Saints interpret the Bible verses saying that all things were created by God?

>All things came into being through Him, and apart from Him **nothing came into being that has come into being**. > >John 1:3 There are also Book of Mormon verses saying that God created all things as well. >There is a God, and he hath created all things, both the heavens and the earth, and all things that in them are. > >2 Nephi 2:14 How do Mormons interpret these verses in accordance with their belief that God was not always God (and so could not have created the things that existed before he became God)?
