Our vacation here is going very well.
We have deduced that your weapons systems are pitiful, your Earf monies are increasingly worthless, and what you consider a "civilization" is secretly engineered by small hairy mammals.
Our home world is overjoyed by the prospect of Earf colonization.
Your cooperation in this matter will guarantee you a full life of toiling and servitude to your new overlords. Independent thought is no longer authorized.
Have a good day!
