Bonjour Isaiah,

I guess every language has its own differences. "Être" and "avoir" are both used differently in French and in English. I am not a Spanish expert so I could not say for sure.

Here are 2 links you might want to read:

How to Use the Spanish Verbs “Ser” and “Estar” [+ Practice]

I hope this is helpful.

Bonne journée !
