The Annunaki are the ones who make up the bloodlines – they mated with humans in order to live among you. They are what you call the long heads but they are Annunaki.

The role of the earthling in this was to be the animal – you were exploited and still are to this day.
When they have sex with your females, it is as if it is the same as your male having sex with sheep.
