"We say 'il faut' in French instead of 'on doit' because 'il faut' is a more common and idiomatic expression in the French language. It is used to convey the idea of necessity or obligation in a more formal and impersonal way. On the other hand, 'on doit' is more direct and personal, implying a specific obligation or duty. Therefore, 'il faut' is preferred in a wider range of contexts and is considered more polite and appropriate in formal or general statements." **
