So you're saying there's a chance I could be treated like a stud and get milked at the milking table for my spatter batter to be sold off for huge amounts of currency and possibly costing more for the buyer if they're wanted their pet human to get the natural/organic injection of my batter?? 
Where is it that I sign? Next to the drawn X?
They could just want the planet, not the energy or resources. Earth is, for all we know, very rare. >

They could also just want us as pets. A pet hooman to amuse them. >

Free food, shelter and breeding?You son of a bitch I'm in! >

even if their idea of pet is so much like ours that the free food is even more like "human kibble" than r/showerthoughts says cereal is, the shelter is crude with no amenities (as even if you're an "indoor human" they wouldn't take too kindly to you using theirs if you even could) and the breeding, assuming you get bred and not forcibly castrated, is with someone you don't even love but has the right genes that your mating could produce a pageant lineage that fits within their arbitrary "human breed standards" for whatever you'd both be considered?
