Jesus is called only-begotten son. Why?

Why is Jesus Christ called only-begotten son in the Bible
Jesus Christ is called only begotten son in the Bible (see John 1:14, 3:16; 1 John 4:9,10 in the Bible). Why?
According to the Bible, God’s Word, Jesus Christ is the first creation of Almighty God Jehovah. In the Bible, John 1:14, Jesus Christ is called only begotten son. Because Jehovah God created Jesus Christ by himself. But then the Creator, Jehovah God, made it possible for Jesus Christ to participate in the creation of all other things. Jesus did not become a co-creator. Instead, he was allowed to create all other things in heaven and on earth with the active power of God (called the Holy Spirit in the Bible). Jesus Christ was used as a master craftsman. Jesus Christ is only one the Creator, Jehovah, used for this.

Every other creation was created by Jesus

In God’s Word, the Bible, we learn that everything else in heaven and on earth was created by Jesus Christ. The visible and the invisible. Everything else, every other creation, was created by Jesus and for Jesus. We learn this in the Bible book Colossians 1:16.
