"First, the name Melchizedek means “king of righteousness”; then also, “king of Salem” means “king of peace.” ³ Without father or mother, without genealogy, without beginning of days or end of life, resembling the Son of God"

This lollypop of yours, has already been sucked dry.
This verse is comparing someone from the past with someone from the future, the Jesus in the hear and now of the times, the Flesh Jesus as NOT a pre-existing Jesus and he only become a Son of God, begotten from his birth from Mary = Bible TRUTH.

This one has been sucked dry as well

⁵ The Son is the image of the invisible God as was the first Adam, the firstborn over all creation in the mind and plans of God, where your creations begin. ¹⁶ For in him for that reason, firstborn in the plans all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through on account of, by reason of, because of, for the sake of (as per the Greeks) him and for him by Yehowah alone and by himself Isa 44:24. ¹⁷ He is before all things, because he was the firstborn of creation in God's plans and in him for the above reasons all things hold together.

1:18 - And He is the head of the body, the church, who is the beginning, the firstborn from the dead, so that in all things He may have the preeminence.

Had he failed his mission, not raised, he would not have preeminence.
Not to mention, if he was the creator and pre-existing, he would already have preeminence DRRRRRRRRRRRRRRR!
