This, of course, ignores that the Greek word MONOGENES is used differently in other parts of the bible. For example, that word is used in relationship to Jacob, and it just so happens that Jacob had brothers. Are you going to tell me that jacob's brothers were not begotten? This is an example of how religious dogma alters translation.
Nonsense.
If that (John 3:16) was the only place in the New Testament or Bible that showed the uniqueness of Jesus as a Son of God, then you might have a case. But it's not and your case is easily demolished. The deity of Jesus is clear and redundant in the NT.
From my prior link / article:
'The second definition is "pertaining to being the only one of its kind or class, unique in kind." This is the meaning that is implied in John 3:16 (see also John 1:14, 18; 3:18; 1 John 4:9). John was primarily concerned with demonstrating that Jesus is the Son of God (John 20:31), and he uses monogenes to highlight Jesus as uniquely God's Son—sharing the same divine nature as God—as opposed to believers who are God's sons and daughters by adoption (Ephesians 1:5). Jesus is God’s “one and only” Son.'
The deity of Jesus Christ
Scholarly author Kevin J. Conner lists 27 initial scriptural evidences demonstrating the deity of Christ:
1. Jesus existed in the beginning (John 1:1; Philip 2:6; Rev. 19:13; Micah 5:2).
2. He was with God (John 1:1).
3.
He is God, the Son (John 1:1; Rom. 9:5; Heb. 1:8, 10; I John 5:20).
4. He is God manifest in the flesh (John 20:28; I Tim. 3:16; Col. 2:9; Acts 20:28; Heb. 1:8).
5. He is God foretold (Isaiah 9:6; Psalm 45:6).
6. He is Immanuel, God with us (Isaiah 7:14; Matthew 1:23).
7. He is the true God (I John 5:20 with Titus 2:13; Romans 9:5).
8. He is the great God (Titus 2:13).
9. He is God our Savior (II Peter 1:1).
10.
He existed in the form of God before His incarnation and was equal with God the Father (Philippians 2:5-7)

And there's dozens of other evidences for the divinity of Christ, which supports the argument that he is not just one of billions of 'sons of God'
