Why the people said that Jesus is the first son of god in earth?

Question

because the bible said that the first one in earth was Adam
Luke 3:38
[son] of Adam,
[son] of God.
Jesus is the first son but in heaven. (Colossians 1:15-17)
We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth ( 1 John 5:19) Here said that God Begat Jesus.
God begat Jesus that word means born like in Matthews 1:2 Abraham begat Isaac; and Isaac begat Jacob.
Jesus is the first but God has more sons because the bible said in Job 1:6 : Now it came to be the day when the sons of the [true] God entered to take their station before Jehovah, and even Satan proceeded to enter right among them.
and Job 2:1
Afterward it came to be the day when the sons of the [true] God entered to take their station before Jehovah, and Satan also proceeded to enter right among them to take his station before Jehovah.

Answer 1

Jesus is the first born of all creation:

Col. 1:15 He is the image of the invisible God, the firstborn of all creation; (dictionary says firstborn is the eldest)

Rev 3:14 “And to the angel of the congregation in La·o·di·ce´a write: These are the things that the Amen says, the faithful and true witness, the beginning of the creation by God,

Jesus was created prior to the other sons of God at Job 1:6

Answer 2

Jesus, is the only person created directly by god, as all other things were created by god through his son jesus.
For clear understanding of scripture you need to understand the principles of poetic language. You see, the Bible also calls the 1st temple, as Built by Solomon, yet Solomon did not personally build the temple, rather he directed the work. Like wise, Adam, was created by God(his creation was directed by God) yet it was Jesus who performed the work.

Answer 3

god doesn't have any children, wife, or partner
