We could also be considered an "endangered plant" and thus off limits to any actual contact. Kinda like an intergalactic protected wetlands.........
That’s logical. We’re fascinating, but icky. Could be worse, we could be a colony gone native and they just can’t figure out who/what is who/what anymore.
Or- they could be the intergalactic paparrazzi and somewhere there’s a tabloid with shocking pics of single-headed monstrosities( us) that make the photographers a fortune.
