NATAL: Worshipping God that Born Later?

There is some question in my mind when seeing the Christians celebrating Chrismast eve, the day that their God is born.

As we know, Jesus is born after the world is created, and he is the descendant of Adam... Abraham, and the husband of Mary, Joseph (though the Gospel says that Mary gave birth to Jesus without having any sexual intercourse with Joseph – SHE IS VIRGIN MARY!)

Look at the Gospel verses as follow:

"3:23 And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli" [Luke 3:23]
"3:38 Which was the son of Enos, which was the son of Seth, which was the son of Adam, which was the son of God." [Luke 3:38]

Gospel says that Adam is the son of God too (look the above verse).
"1:16 And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ.
1:17 So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon unto
Christ are fourteen generations.
1:18 Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost." [Matthew 1:16-18]

My questions are:

1. Do Adam, Abraham, Moses, etc, and its followers should worship the unborn "God," Jesus?
2. If Jesus born later than Adam, Abraham, Moses, etc, then which God create the world, Adam, Abraham, Moses, etc? Shoud God is the creator of the whole universe, and He should exist before its creatures and create them all?
3. By that condition, Is Jesus a God, or just simply human that given some miracles (just like Moses who could turn his stick into a snake or crossing the Red Sea) by God?
4. Is Santa Claus really exist? Why do the parents and many movies try to convince (or lie?) children that Santa Claus is really exist? Is it the true religion should teach the truth and only the truth to its follower?

Look the Quran verses that says Jesus is the son of Mary (not the son of
Joseph or God):

"And behold! Allah will say: "O Jesus the son of Mary! didst thou say unto men, 'Worship me and my mother as gods in derogation of Allah'?" He will say: "Glory to Thee! never could I say what I had no right (to say). Had I said such a thing, Thou wouldst indeed have known it. Thou knowest what is in my heart, though I know not what is in Thine. For Thou knowest in full all that is hidden."
[Quran Al Maidah:116]

"They do blaspheme who say: "Allah is Christ the son of Mary." But said Christ: "O Children of Israel! Worship Allah, my Lord and your Lord."
Whoever joins other gods with Allah, Allah will forbid him the Garden, and the Fire will be his abode. There will for the wrongdoers be no one to help."
[Quran Al Maidah:72]

God does not forgive the sin of joining other gods with Him:

"Allah forgiveth not (the sin of) joining other gods with Him; but He forgiveth whom He pleaseth other sins than this: one who joins other gods with Allah, hath, strayed far, far away (from the Right)."
[Quran An Nisaa:115]


"Allah has said: "Take not (for worship) two gods: for He is just One God: then fear Me (and Me alone)."
[Quran An Nahl:51]

"Say: if there had been (other) gods with Him, - as they say - behold, they would certainly have sought out a way to the Lord of the Throne!"
[Quran Al Isra:42]

"If there were, in the heavens and the earth, other gods besides Allah, there would have been confusion in both! But glory to Allah, the Lord of the Throne: (High is He) above what they attribute to Him!"
[Quran Al Anbiyaa:22]

"No son did Allah beget, nor is there any god along with Him: (if there were many gods), behold, each god would have taken away what he had created, and some would have Lorded it over others! Glory to Allah! (He is free) from the (sort of) things they attribute to Him!"
[Quran Al Mu’minuun:91]
