Invading a place that wants to kill you is not that unheard of. Some of us explore flanks of erupting volcanoes, abysses, or want to go to space/the Moon/Mars.

Going there naked, and with absolutely no idea what you’re exposing yourself to, is bonkers though. Especially absurd for the crew of a spaceship with interstellar capability. How the hell did they reach Earth without killing themselves a thousand times on their travel?
