I seriously don't understand how you could think he had consummated his marriage with Aisha at that time if you've been studying Islam for 12 years. I'm thinking you've been studying anti-Islamic propaganda for 12 years.. and not very well.
There were things experienced and witnessed by those around Prophet Muhammad (pbuh). You haven't come across any in 12 year research?
At least we know who our telephone players were.
How long have you been a Muslim? Have you not studied all this?
In 621 Aisha was 9 years old.
If you are going to take any hadith as trusted then you must also take the bad and ugly ones too:
Sahih Al-Bukhari, Volume 5, Book 58,
Number 234
Narrated Aisha:
The Prophet engaged me when I was a girl of six (years). We went to Medina and stayed at the home of Bani-al-Harith bin Khazraj. Then I got ill and my hair fell down. Later on my hair grew (again) and my mother, Um Ruman, came to me while I was playing in a swing with some of my girl friends. She called me, and I went to her, not knowing what she wanted to do to me. She caught me by the hand and made me stand at the door of the house. I was breathless then, and when my breathing became all right, she took some water and rubbed my face and head with it. Then she took me into the house. There in the house I saw some Ansari women who said, "Best wishes and Allah's Blessing and a good luck." Then she entrusted me to them and they prepared me (for the marriage). Unexpectedly Allah's Apostle came to me in the forenoon and my mother handed me over to him, and at that time I was a girl of nine years of age.

Then you were shown to me, the angel carrying you in a silken piece of cloth, and I said (to him), 'Uncover (her), and behold, it was you.

She further said: We went to Medina and I had an attack of fever for a month, and my hair had come down to the earlobes. Umm Ruman (my mother) came to me and I was at that time on a swing along with my playmates. She called me loudly and I went to her and I did not know what she had wanted of me. She took hold of my hand and took me to the door, and I was saying: Ha, ha (as if I was gasping), until the agitation of my heart was over. She took me to a house, where had gathered the women of the Ansar. They all blessed me and wished me good luck and said: May you have share in good. She (my mother) entrusted me to them. They washed my head and embellished me and nothing frightened me. Allah's Messenger (may peace be upon him) came there in the morning, and I was entrusted to him.

SUNAN IBN-I-MAJAH
1876. Aisha (Allah be pleased with her) is reported to have said: Allahs Messenger (peace and blessings of Allah be upon him) contracted marriage with me while I was (yet) a six years [sic] old girl. Then we arrived at Medina and stayed with Banu Harith b. Khazraj. I fell victim to fever; then my hair (of the head fell off (and became scattered). Then they became plenty and hanged down upto [sic] the earlobes. My mother Umm Ruman came to me while I was (playing) in a swing alongwith [sic] my play-mates. She (the mother) called me loudly. I went to her and I did not know what he [sic] wanted. She seized my hand and stopped me at the door of the house and I was hearing [sic] violently until the agitation of my heart was over. Then she took some water and wiped it over my face and head. Then she admitted me to the house when some woman [sic] of Ansar were present in the house. They said, "You have entered with blessings and good fortune." Then she (the mother) entrusted me to them. So they embellished me and nothing frightened me but Allahs Messenger (peace and blessings of Allah be upon him) (when he came there) in the morning and they (the women) entrusted me to him. On that day, I was a nine years [sic] old girl."
1877. Abdullah (Allah be pleased with him) is reported to have said, "The Holy Prophet (peace and blessings of Allah be upon him) married Aisha while she was a seven years [sic] old girl and took him [sic] to his house as a bride when she was nine years old and he parted with her (after his demise) when she was eighteen years old."
According to Al-Zawaid its isnad is sahih in accordance with the condition prescribed by Bukhari, but munqata because Abu Ubaida did not hear from his father. Shuba Abu Hatim and Ibn Hibban mentioned him amongst the authentic and reliable authorities. Tirmidhi in al-Jami and al-Mazzi in al-Atraf (has expressed the same opinion). Nasai has transmitted this hadith in al-Sughra from the hadith Aisha (Allah be pleased with her). (Sunan Ibn-I-Majah, Imam Abdullah Muhammad B. Yazid Ibn-I-Maja Al-Qazwini, English version by Muhammad Tufail Ansari [Kazi Publications, 121-Zulqarnain Chambers, Gampat Road, Lahore Pakistan, first edition, 1995], volume III, pp. 133-134)
IBN HISHAM
He married Aisha in Mecca when she was a child of seven and lived with her in Medina when she was nine or ten. She was the only virgin that he married. Her father, Abu Bakr, married her to him and the apostle gave her four hundred dirhams. (Ibn Ishaq, Sirat Rasulullah (The Life of Muhammad), translated by Alfred Guillaume [Oxford University Press, Karachi, tenth impression 1995], p. 792)
AL-TABARI
In this year also the Messenger of God consummated his marriage with Aishah. This was in Dhu al-Qadah (May-June 623) eight months after his arrival in Medina according to some accounts, or in Shawwal (April-May 623) seven months after his arrival according to others. He had married her in Mecca three years before the Hijrah, after the death of Khadijah. At that time she was six or, according to other accounts, seven years old.
According to Ab al-Hamid b. Bayan al-Sukkari- Muhammad b. Yazid- Ismail (that is, Ibn Abi Khalid)- Abd al-Rahman b. Abi al-Dahhak- a man from Quraysh- Abd al-Rahman b. Muhammad: Abd Allah b. Safwan together with another person came to Aishah, and Aishah said (to the latter), "O so-and-so, have you heard what Hafsah has been saying?" He said, "Yes, O Mother of the Faithful." Abd Allah b. Safwan asked her, "What is that?" She replied, "There are nine special features in me that have not been in any woman, except for what God bestowed on Maryam bt. Imran. By God, I do not say this to exalt myself over any of my companions." "What are these?" he asked. She replied, "The angel brought down my likeness; the Messenger of God married me when I was seven; my marriage was consummated when I was nine; he married me when I was a virgin, no other man having shared me with him; inspiration came to him when he and I were in a single blanket; I was one of the dearest people to him, a verse of the Quran was revealed concerning me when the community was almost destroyed; I saw Gabriel when none of his other wives saw him; and he was taken (that is, died) in his house when there was nobody with him but the angel and myself."
