Something was revealed to me after some discussion with the vampires.
The 3rd period of the ages of man, Moloch, ended up killing every single human. They created the egregore and killed all their children, then suicided so that they would all be joined in this egregore as a hivemind.
It's the story told in the anime Neon Genesis Evangelion. There never was any saving them, they turned into the blood-soup in the end. I saw this in a dream two days ago but didn't understand why it looked like that. Then I saw some pro-abortion female on tv and she had this type of energy all over her. They're doing what they do because they want everyone to kill their children and themselves to join the Moloch egregore. They don't want anyone to survive.

The only people remaining were reptilians and vampires. The followers of Cain had tasted his blood and were able to avoid the slaughter because of their supernormal abilities. But they weren't truly undead so they were able to have children. They recreated humanity from a group of a less than 100. This the reason why there's been talk such as
>when humans die out, we will be able to sustain ourselves by hunting animals
It has happened before.
