Turn this sentence into a negative using double negation Hay alguien aquí?

The sentence "Hay alguien aquí?" translates to "Is there anyone here?". Here are a couple of ways to make it negative using double negation:

1. Formal: "No hay nadie aquí." (There is no one here.)

2. Informal: "No es que haya nadie aquí." (It's not that there is anyone here.)

The second option is a bit more emphatic and a little less common in everyday speech.
