If an alien civilization had the means to discover us on earth and then somehow travel the unimaginably vast distance to come visit us, they would ipso facto cruise right past us to somewhere more interesting.
It would be like if you stopped and investigated every ant hill you passed while walking down the street. Of course no one does that, because who the fuck cares about an ant hill, we’ve got shit to do.
So no way would they waste time beaming us up and probing our rectums or making crop circles or mutilating our cows... they’ve got a fucking Dyson sphere to build in the Crab Nebula. And if they have the capacity to do all that other shit, I’m pretty sure they could deduce all they’d ever need to know about our precious rectums without actually beaming us on board for the full exam. You feel me?
