  Hey imakemoney,
  
  Well, this would be tricky. I’ve seen enough Alien films to know that shooting them with rockets and missiles isn’t the way to go. We’d have to think carefully about this one. We obviously wouldn’t be able to speak their language so observing what they eat would be a good place to start (which hopefully isn’t humans). Once we know their diet we could try and offer them some kind of free food to show them we mean to harm.
  
  Everyone loves free food. Hopefully this would keep them happy and stop them wiping out humans!
