Oh like you wouldn't visit a planet so filled with poison that it actually exists in the air itself!
I would, but I'd have at least worn a space suit instead of walking around butt naked. Something about that no visible genitalia thing just makes aliens want to go running around in their birthday suits.
I'd also bring a Transphasic Quantum Magnetometric GPS or two so I don't have to rely on crop circles to guide my spaceships in for a landing, but that's just me.
It's almost as if the aliens were the Griswolds of space and the Earth was the galaxy's largest ball of mud that they wanted to visit on a whim while heading somewhere else.
