You will find that I have quoted authentic hadith of Sahaih Al Bukhari with a link to the arabic text which clearly narrates that The age of Prophet Muhammad's (PEBH) wife Ayesha was 6 years old when married and was 9 years old when the marriage was consummated, if you read it it even tells that her mom brought her from outside while she was playing, washed her face, took her into the tent and presented her to the Profi (PEBH)

I guess you need to refer to this and advise if you trust this is an authentic source or you believe Sahih Al Bukhary lack authenticity
