"Sir, we have incoming fire."
"Ensign, what are they firing at us?"
"Lasers? But that won't even penetrate our navigation shields."
"Looks like they're hailing us sir"
"OK, let's humor them and see what they want..."
Maybe they just want our planet. period. Maybe they need a new vacation spot. Maybe they just like salty oceans and sandy beaches. Those darn apes are in the way, so they'll have to remove them first. They're funny. The apes think they're intelligent (they have built a few small structures); so, we'll have some fun with them first.....
