What Question Would You Ask An Alien.?

if intelligent lives were discovered to be present somewhere else in the universe order than the earth and it is possible to communicate with them (it take roughly 20 years for the message and answer to come through).

Everyone on earth is asked to submit 2 questions for the aliens

if NASA and other sponsors of this project were offering a million dollars each to people with the best 5 questions, what question would you ask these aliens.

P.S. These guys don't look like we human beings, they have 2 heads, 5 hands, and they probably survive on some sort of mind bugling element too. It was also discovered that the aliens have the necessary technology to send and receive radio signals in form of text messages or low resolution images. The aliens also understand basic human languages.
