I had once heard that the ark rested on Mt Ararat in the north. I asked Utnapishtim about this.

"You mean the Hebrew word 'Ararat'? 'Har - arad' or 'hill of descent'? All of my descendants will descend from this place. This is our new 'hill of descent' just as the northern mountains were 'hills of descent' thousands of years ago. But I don't know why you use the Hebrew word. We speak Sumerian. I called my underwater hill 'kur nisir'. A 'kur' is a land or hill but not a mountain. 'Nisirtu' just means inaccessible."

Should I ask him how he became immortal? Or should I ask what immortality means?

Or should I ask something else?
