Oh, you think you’re the more intelligent race but we’ve been here for 1000 years spying on your every move. Yes, we were sent as robots to spy on you until the day when we gather enough information for the invasion. If you ever looked closely you could see the mechanical way that we move and understand our true mission but “you’re just too smart” to see what’s right in front of you. Cute you little squirrel and chipmunk who were built for a more devious mission.
