Hadith are subject to scrutiny. They are NOT the word of God. I have you a list of reasons why it is POSSIBLE that Aisha (RA) was NOT 9 years old.
So it NOT a proven FACT that she was 9. But since you have developed such a hatered for Islam, that you are inclined to believe anything and everything that tried to defame Islam. That is what we call "BIAS"
I have a BIAS towards Islam, you have a BIAS against Islam.
