Jehovah's Witnesses

Well, that would have been Jesus, Gods son, the first of his creation, as is shown at Colossians 1:15 "He is the image of the invisible God,+ the firstborn of all creation;+ 16 because by means of him all other things were created in the heavens and on the earth, the things visible and the things invisible,+ whether they are thrones or lordships or governments or authorities. All other things have been created through him+ and for him. 17 Also, he is before all other things,+ and by means of him all other things were made to exist"

Also 1Corinthians 8: "there is actually to us one God,+ the Father,+ from whom all things are and we for him;+ and there is one Lord, Jesus Christ, through whom all things are+ and we through him."
