The Reptiloids are key players in the Konspiratsia Soverishejdj, having long ago decided that they should take-over Earth for some reason. That reason has something to do with the fact that the reptiloids used to live here, way back in the Cretaceous, and even though they've been gone for something like 65 million years apparently they think they still own the damned place. Frankly, who are we to argue with them?
