What is the significance of the existence of French mute H?

Haha, I am a French teacher. When I teach French, I like to compare English with French. Although H is silent, keeping it can make the analogy between English and French more similar. Like histoire and history hero and heroH? Sometimes students can guess the meaning of French words according to English, and occasionally help students remember French words. We often memorize pronunciations first according to their spelling. What about the silent letter h? Think about the analogy of English words. Hehe, of course, the scenery on the first floor above is also very reasonable.
