Well, your alleged "Bible scholars" need some serious help.
Why don't you ask them why Luke records what transpired when Jesus was 12 YEARS OLD in the temple?
You know, this:
Luke chapter 2
[
40] And the child grew, and waxed strong in spirit, filled with wisdom: and the grace of God was upon him.
[
41] Now his parents went to Jerusalem every year at the feast of the passover.
[
42]
And when he was twelve years old, they went up to Jerusalem after the custom of the feast.
[
43] And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and Joseph and his mother knew not of it.
[
44] But they, supposing him to have been in the company, went a day's journey; and they sought him among their kinsfolk and acquaintance.
[
45] And when they found him not, they turned back again to Jerusalem, seeking him.
[
46]
And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions.
[
47]
And all that heard him were astonished at his understanding and answers.
[
48] And when they saw him, they were amazed: and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I have sought thee sorrowing.
[
49] And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?
[
50] And they understood not the saying which he spake unto them.
[
51] And he went down with them, and came to Nazareth, and was subject unto them: but his mother kept all these sayings in her heart.
[
52] And Jesus increased in wisdom and stature, and in favour with God and man.

"Verse 42: "And when he was 12 years old they went up according to the custom." The fact that this incident happened when Jesus was 12 is probably significant. The 12th year was the final year of preparation for a lad before he entered full participation in the religious life of the synagogue. Up until that time his parents, especially his father, were teaching him the commandments of the law, but at the end of the 12th year the child goes through a ceremony by which he formally takes on the yoke of the law and becomes a
bar mitzvah or "son of the commandment." This was the year Jesus chose to stay behind in the temple. Perhaps, at this crucial turning point in every Jewish boy's life, Jesus wanted to demonstrate subtly for those who had eyes to see that he would be more than an ordinary Jewish
bar mitzvah; his insight into the commandment was more profound than ordinary men, and his relation to God was unique. Both of these will be evident in a moment."
