You are just full of assumptions. How do you get that Jesus preexisted creation? It is a historical fact Jesus was born in Bethlehem in about 2 B.C. I don't know of anyone who believes that Jesus the man was around when God created the physical world.
Also when you bring in NT Scriptures that are not the fulfillment of the Messianic prophesies you are taking this thread off topic. There are two other threads dealing with the NT and why Jesus is not God.
And you are avoiding what Scripture tells us in Genesis 3 and 22 with you fairy tale story that God created a special egg and implanted it in Mary.
Genesis 3:15
15 And I will put enmity
Between you and the woman,
And between your seed and her seed;
He shall bruise you on the head,
And you shall bruise him on the heel. " NAS
Genesis 22:15-19
15 Then the angel of the LORD called to Abraham a second time from heaven, 16 and said, "By Myself I have sworn, declares the LORD, because you have done this thing, and have not withheld your son, your only son, 17 indeed I will greatly bless you, and I will greatly multiply your seed as the stars of the heavens, and as the sand which is on the seashore; and your seed shall possess the gate of their enemies. 18 And in your seed all the nations of the earth shall be blessed, because you have obeyed My voice." 19 So Abraham returned to his young men, and they arose and went together to Beersheba; and Abraham lived at Beersheba. NAS
So the fact that Abraham was the father of Isaac, who was the father of Jacob whose name was changed to Israel, who was the father of Judah, which is the tribe that produced David is irrelevant to God's truth? Then why do you think Matthew started his genealogy with Abraham and not David?
Your interpretation of Scripture is weird to say the least especially in view of what both Jesus and Peter said:
Matthew 22:41-46
41 Now while the Pharisees were gathered together, Jesus asked them a question,42 saying, "What do you think about the Christ, whose son is He?" They said to Him, "The son of David." 43 He said to them, "Then how does David in the Spirit call Him 'Lord,' saying,
44'The Lord said to my Lord,
"Sit at My right hand,
Until I put Thine enemies beneath Thy feet"'?
45 "If David then calls Him 'Lord,' how is He his son?" 46 And no one was able to answer Him a word, nor did anyone dare from that day on to ask Him another question.
NAS
Acts 2:22-31
22 "Men of Israel, listen to these words: Jesus the Nazarene, a man attested to you by God with miracles and wonders and signs which God performed through Him in your midst, just as you yourselves know-- 23 this Man, delivered up by the predetermined plan and foreknowledge of God, you nailed to a cross by the hands of godless men and put Him to death. 24 "And God raised Him up again, putting an end to the agony of death, since it was impossible for Him to be held in its power. 25 "For David says of Him,
'I was always beholding the Lord in my presence;
For He is at my right hand, that I may not be shaken.
26 'Therefore my heart was glad and my tongue exulted;
Moreover my flesh also will abide in hope;
27 Because Thou wilt not abandon my soul to Hades,
Nor allow Thy Holy One to undergo decay.
28 'Thou hast made known to me the ways of life;
Thou wilt make me full of gladness with Thy presence.'
29 "Brethren, I may confidently say to you regarding the patriarch David that he both died and was buried, and his tomb is with us to this day. 30 "And so, because he was a prophet, and knew that God had sworn to him with an oath to seat one of his descendants upon his throne, 31 he looked ahead and spoke of the resurrection of the Christ, that He was neither abandoned to Hades, nor did His flesh suffer decay. NAS
Now if God created a special egg that is not of David's line either Scripture is false or your interpretation is nothing more than a pipe dream you are trying to use to avoid God's promises made to both Abraham and David. And since God cannot and does not lie I will take His word over yours.
