THIS. I don't think they are aliens. I think they're some kind of Neanderthal hybrid that had an advanced civilization at the end of the last Ice Age.
The civilization was destroyed by a comet but some refugees survived. They decided it was comfier to be worshipped / provisioned by primitive H. Sapiens than to increase their own numbers and risk their lifestyle.
These guys are the source of elongated skulls in Peru, among the Pharaohs and among modern bloodlines such as D'Este, Rothschild, and various Vatican bloodlines.
If you read that 'Rofschild' disclosure you will see that they want to use the Rhesus blood type reaction to permanently brifucate the species into themselves and the rabble, with a 100pt. IQ difference between them. If they get their way with their welfare state and other social engineering plans then we will literally become LIVESTOCK. Forever.
