6- is it logical to judge a marriage case that took place before 1400 years under the laws of the 21st century?

after demonstrating the age of consent for the american girl, which was until the last part of the 19th century just ten years i.e. one year older than aisha when she married the prophet – peace and blessings of allah be upon him – 13 centuries ago; moreover, such age was just seven years in one of the american states i.e. two years younger than aisha – may allah be pleased with her, and having demonstrated that the age of consent is still ranging between twelve to thirteen years in most countries of the world, including western and christian countries; accordingly, there is no ground to criticize the marriage of the prophet – peace and blessings of allah be upon him – and aisha – may allah be pleased with her – which was portrayed by the instigators as an offence against young girls. such instigators exploited the ignorance of the western community about the age of consent in the west and the non muslim countries in order to instigate against islam and portray the prophet of islam – peace and blessings of allah be upon him – as an offender. such instigators are in fact hypocrite people because they are accusing the muslims with things practiced legally and normally by non muslims.
 
in brief, the early marriage still exist in the 21st century, and it is practiced by european and christian people in the 21st century; therefore, why is the prophet of islam – peace and blessings of allah be upon him  –blamed for such marriage which took place before 1400 years? this clearly demonstrates the non credibility of such instigators and their hidden aims under the pretext of defending the rights of woman and the human rights in order to gain the sympathy of the western people toward aisha the child who was "obliged" to marry a man more than fifty years old, as they allege. however, apart from the instigation of such criticizers who have concealed their actual aims, we would like to demonstrate some points about the marriage of the prophet of islam – peace and blessings of allah be upon him – and aisha – may allah be pleased with her – when she was nine years old, in order to understand the reasons and circumstances of such marriage.
 
did they know the arabian peninsula before 14 centuries?

it is worth mentioning that the western principles and mentality in the 21st century may not understand the eastern & arabian principles and mentality in the 6th century fully and completely! there is a wide gap between the two cultures, mentalities, and geographies. this is an important point which should be recognized, because judging a norm practiced by an eastern community before fourteen centuries by a secular western culture in the 21st century won't be just or accurate. therefore, the western people in this era should study such norm and understand the reasons which justify it. anyway, such reasons are still convincing the western and christian communities which do not oppose the early marriage until today.
