Why is French the language furthest from Latin?

At the end of the 2nd century BC, Roman merchants went to some towns in Gaul to conduct business activities. Roman immigrants appeared in southeastern Gaul. After Gaul became a Roman province, Rome not only ruled Gaul politically, but also stepped up immigration to Gaul, penetrated it culturally, and promoted Romanization. Because Gaul did not have its own written language, it created conditions for the promotion of Latin. Latin was the official language used by the Romans and the language of commerce within the Roman Empire. After Gaul became a Roman province, Latin became fashionable among the upper classes and became a status symbol. In this way, Latin gradually replaced Celtic as it spread among the people through traders and immigrants. The Latin in Gaul evolved over a long period of time into the Romance languages ??of the Middle Ages, and later became today's French. So Paris had Qartier Latin, and Latin became one of the official languages ??alongside French until the end of the 18th century. In addition, Latin and French are also indispensable tools for students studying liberal arts - having basic knowledge about historical eras and understanding the time frames of major historical events are prerequisites for successful history study. Foreign languages ??require mastery of Latin, French and English: Latin is used to read ancient Greek, Roman and medieval texts; French and English are international documents and scientific languages.
