God knows.
Jesus was born man. Jesus is God's human form. He sent Jesus to Earth because He wanted to get people to believe in Him. After all God did create all human kind and every living creature/thing.
Some other Answer:
Consider that each of us is a thought of God. Consider that Son of Man, means, that the birth of Jesus, as a man, was the product, or son, of mankind's cumulative love for humanity, thus being the Son of Man and at the same time, Son of God. This is just my thought… I don't claim to be right.
Jesus was not "chosen" to be the Son of God. Jesus is God the Son, the Second Person of the Blessed Trinity, which existed for all eternity. Jesus was begotten by God the Father before time existed, and so Jesus is eternal (as opposed to everlasting, like created man). Jesus was God before His incarnation to become Man. Jesus is the only Person who has a true God nature and true Human nature. He is fully God and fully Man. He therefore has two wills, a Divine Will and Human Will.

Christ Jesus, "the Son of Man." In the Gospel accounts the expression is found nearly 80 times, applying in every case to Jesus Christ, being used by him to refer to himself. (Mt 8:20; 9:6; 10:23) The occurrences outside the Gospel accounts are at Acts 7:56; Hebrews 2:6; and Revelation 1:13; 14:14. Jesus' application of this expression to himself clearly showed that God's Son was now indeed a human, having 'become flesh' (Joh 1:14), having 'come to be out of a woman' through his conception and birth to the Jewish virgin Mary. (Ga 4:4; Lu 1:34-36) Hence he had not simply materialized a human body as angels had previously done; he was not an incarnation but was actually a 'son of mankind' through his human mother.-Compare 1Jo 4:2, 3; 2Jo 7; For this reason the Apostle Paul could apply Psalm 8 as prophetic of Jesus Christ. In his letter to the Hebrews (2:5-9), Paul quoted the verses reading: "What is mortal man ['enohsh′] that you keep him in mind, and the son of earthling man [ben-'a·dham′] that you take care of him? You also proceeded to make him a little less than godlike ones ["a little lower than angels," at Hebrews 2:7], and with glory and splendor you then crowned him. You make him dominate over the works of your hands; everything you have put under his feet." (Ps 8:4-6; compare Ps 144:3.) Paul shows that, to fulfill this prophetic psalm, Jesus indeed was made "a little lower than angels," becoming actually a mortal "son of earthling man," that he might die as such and thereby "taste death for every man," thereafter being crowned with glory and splendor by his Father, who resurrected him.-Heb 2:8, 9; compare Heb 2:14; Php 2:5-9. The designation "Son of man," therefore, also serves to identify Jesus Christ as the great Kinsman of mankind, having the power to redeem them from bondage to sin and death, as well as to identify him as the great Avenger of blood.-Le 25:48, 49; Nu 35:1-29; Thus, Jesus' being called the "Son of David" (Mt 1:1; 9:27) emphasizes his being the heir of the Kingdom covenant to be fulfilled in David's line; his being called the "Son of man" calls attention to his being of the human race by virtue of his fleshly birth; his being called the "Son of God" stresses his being of divine origin, not descended from the sinner Adam or inheriting imperfection from him but having a fully righteous standing with God.--- Insight on the Scriptures vol2, published by Watchtower Bible and Tract Society of New York
In some Gospels Jesus does not directly say that he is the Messiah or the Son of God. 'The Son of Man' is humbler and more obviously truthful.
This phrase originates in Mark's Gospel, where Jesus referred to himself as the Son of Man and Peter called him the Christ ('anointed one'). To have called Jesus the Son of God might have been considered blasphemous when Mark was written, but the demons and the centurion, as outsiders, could call do so because their statements would not bring the Christian community into disrepute.
Perhaps fifteen years later, Matthew's Gospel could use the term Son of God quite freely and sarcasm was no longer necessary in the centurion's statement when Jesus died.
Because the world was lost and doomed to sin so he sent Jesus to save the world so that all who followed him could find their way to God.
