We were wrong

I don't think this will be the case because for it to be believable and not too stupid,but what if we humans are the prize?We are under the inpression that the Xenos are the weapon and we are the little children of the Jockeys.Now,reverse the concept-what if there is something in us that makes us the weapon,and the Xeno's are the children.What if they have two groups trying to get us just like Weyland and Yutani want the Xenos? And whatever they need us for can only be done somewhere else-like say they send us to a planet so we wipe out that species?Maybe we are the dangerous species,look how easily we cause extinction to our own planet.It is a weird idea,but maybe it is they have the giant head and weird maps all over our planet to make us think they are the Kings but in actuality,we are being sent there to wreck havoc?
