The Father, Jehovah God created Jesus:
Rev. 3:14 says that Jesus is "the Beginning of the creation of God". NASB
John 1:18 says that Jesus is God's "only BEGOTTEN Son". ASV
Col. 1:15 says that Jesus is "the FIRSTBORN of all creation".
To further show that Jesus is the first creation of God ("beginning of creation"), Prov. 8:22-30 should also be addressed. The understanding that "Wisdom" in these verses is, in reality, figurative of Jesus in his pre-human existence has always existed in the majority of churches that call themselves Christian. Note even the following trinitarian translations of Prov. 8:22 - "The LORD [Jehovah] created me at the beginning of his work" - RSV, and NRSV.
The scriptures show that Jehovah God (and only Jehovah) has always existed (Ps. 90:2). Since he is from eternity and has obviously always been wise, then Jehovah's own personal wisdom has always existed; it never was created or produced. And since wisdom cannot exist apart from a personality who is capable of using it, and, since the "Wisdom" of Prov. 8:22-30 came into existence before the rest of creation, it cannot represent the wisdom of any other creature (whether angels or men) but a "firstborn Son".
Micah 5:2 says that Jesus' "origin is from of old, from ancient days" - RSV, cf. JB, NEB, REB, NAB, NIV, AT, Mo, NRSV, NJB, Byington, and Young's.)
(Origin: "a coming into existence" - Webster's New World Dictionary, 1973.)
