Alien genetic manipulation.
Charmaine claims she learned from her abductors that all humans today are byproducts of alien genetic manipulation, some more than others.
At certain points in our history, different ET races have come to this planet. And they have not manipulated all of humanity, but certain groups.
The reason and agenda for alien intelligences to be on this planet manipulating humans and animals is because there are wars out there between different types of intelligences about territories and that those territorial wars involve populations of created and manipulated life.
