I hope no sper powerful alien finds theartifacts that we left on the moon. They include bags of poop and pee. If they mistake that for tootsie rolls and lemonade we could be in a world of hurt. :-O
I know you are curious, but I've already had my prostate exam this year...
How about:
"Say could you park your flying saucer somewhere else? You are on-line :-("
Do you believe in God?:angel:
Hola! Tiene usted alguna tacos?
Oh wait, you meant Space Aliens.
I would probably ask for some sort of replicator device (like on Star Trek), and maybe a spin around the galaxy.
After that, they could probe me all they want.
