Finally, after all my adventures, I made it! I am here!

I have arrived at the land of Dilmun! I am face to face with Utnapishtim and his wife, Naamah! About to speak to the only people survived the Great Flood! The only man who the gods gave immortality! I have so many questions! What should I ask first?

Should I ask about the great flood? Or about how the gods caused it? Or how they survived when everybody else died? Or why the ark came here and not the northern Ararat mountains? Or why the gods gave them immortality? Or how immortality works? Or something else?
