"Nous sommes ici."
Here's a breakdown:
* Nous: We
* Sommes: Are (present tense of être, the verb "to be")
* Ici: Here
You can also use other phrases depending on the context, like:
* On est là. (More informal, meaning "We are there.")
* Voici. (This is a more formal way to say "Here is/are," often used when presenting something.)
