We all know that one key attribute of God is that He is eternal. If someone asks you, “Could God create another God?” the answer will be a definite no. Because God is eternal and is not a creation. So how can an eternal person be created? It does not make any sense. Now when we read the Bible, we see that Jesus was created. If Jesus was a creation, then he cannot be the Creator and therefore cannot be God. 

Romans 9:29

For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.

Colossians 1:15

Who is the image of the invisible God, the firstborn of every creature?

Revelation 3:14

And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God. 

How can Jesus be the first born and the beginning of creation if he was the Creator?

Also, the New Testament, acts 13:33 to be precise quotes a verse from the Old Testament…

Psalms 2:7

I will declare the decree: the LORD hath said unto me, thou art my son; this day have I begotten thee. (See also Acts 13:33)

The New Testament author says that this verse is referring to Jesus. But look at the verse. The Lord said, “THIS DAY, have I begotten thee” So Jesus became the begotten Son of God on a certain day. Therefore, he is not the eternal Son of God, which then leaves us to the undeniable conclusion that Jesus is not God.
