Real age of prophet Muhammad (pbuh) wife ayesha(ra)

People are blaming hazrat Muhammad(pbuh) married a 9 years old girl (hazrat ayesha(ra)
There is just one hadith about her age and that is not authentic but who have hate for Muhammad (pbuh) they always ask about this
Her age was 19 instead of nine at the time of marriage

Hisham bin Urwah is the main narrator of this hadith. His life is divided into two periods: in 131A.H. the Madani period ended, and the Iraqi period started, when Hisham was 71 years old. Hafiz Zehbi has spoken about Hisham’s loss of memory in his later period. His students in Madina, Imam Malik and Imam Abu Hanifah, do not mention this hadith. imam malik and the people of Madina criticised him for his Iraqi hadiths.

Historian Ibn Ishaq in his Sirat Rasul Allah has given a list of the people who accepted Islam in the first year of the proclamation of Islam, in which Hazrat Aisha’s name is mentioned as Abu Bakr’s “little daughter Aisha”. If we accept Hisham’s calculations, she was not even born at that time.

Hazrat Aisha narrates that she was present on the battle field at the Battle of Badar (Muslim). This leads one to conclude that hazrat Aisha moved into the Prophet’s house in 1 A.H. But a nine-year-old could not have been taken on a rough and risky military mission.

In 2 A.H, the Prophet refused to take boys of less than 15 years of age to the battle of Uhud. Would he have allowed a 10-year-old girl to accompany him?
There are many other evidences which showing her age were 19 instead of 9
