Rashi: Were you before Adam ha'Rishon? The prefix Hei shows astonishment, therefore there is Chataf Patach under it. Were you born before Adam ha'Rishon, who was formed from the ground, that you know to fulfill all the Chochmah of the Mitzvah of the Creator?

Malbim: You complain about man's creation - why did Hashem create him like this, and not differently? The way he is, it would have been better that he not be created. It is as if you are the first man to be born, and they want to create you.

Malbim: Were you conceived during the six days of creation, before the hills were created, and Hashem wanted to finish your creation and cause you to be born?!
