Let's Invade Saturn

Why do we always assume we're the wimpiest, dumbest life in the universe? We've been getting our cities blown up and our citizens smushed in movies by every alien in the solar system from War of the Worlds to Prometheus. Last time I checked, the Hubble hasn't seen any other planet sending cool remote control buggies to Mars! Let's just go all in on this, humans. Strap some lasers onto a shuttle, head for Saturn. Worst-case scenario, they're as far along as the 1950's. Way more likely we'll be melting horse-drawn carriages or spooking the fleas off cave people diving for cover. Our species rules, let's flex our intergalactic muscle and kick some sand around on this beach!
