Lifeforms capable of living on earth (genetically compatible with us to some extent since we were genetically engineered from them and homo erectus) who are living on a planet which at the outer reaches of it's orbit reaches ~440 astronomical units from the sun. That's one hell of a winter that lasts the better part of 3k years.
So they travel to earth to genetically engineer slaves (us) to mine gold for them
so they can shield their atmosphere, because you know they need their atmosphere... and it's a really good thing they didn't need it until after they somehow developed interstellar transport and genetic engineering!
Of course they're mindless dolts since they think it's easier to come here, genetically engineer humans, and mine enough gold to shield their atmosphere, rather than to just come here and live somewhere hospitable.
The only interesting question this raises is how are you posting here without your brain Berzerker?
