Well, that would also be suggested by this transcript:

Q: (L) I was reading some of the transcripts earlier today. One of the things I read was about the Nephilim and their interactions with human beings and about other planets and molecularization, etc. Then, I was reading about the planet Kantek. Are there any human beings, on Earth, at the present time, who carry in them the Nephilim genes?
A: Yes.
[...]
Q: (L) Would these Nephilim genetics be passed down in the natural way, or would they be the result of genetic manipulation by genetically altering a fetus and then putting it back?
A: No to latter. One clue: double Y chromosomes.
Q: (W) That's male...
A: Nephalim were.
Q: (L) They, were male. Women are a double X, men are XY.
A: Prisons are filled with double Y's with monstrous personality disorders, almost always Caucasian and over-sized.
Q: (L) On TV they interviewed a serial killer. He was HUGE! He described killing. The shrink who was analyzing said he did it because he wanted to get caught. I did NOT get that feeling. I think he did it just because it was what he did. [...] Big. Caucasian. My, my, my. Is there any other clue you can give?
A: Nephalim are not currently on your world, just trace residuals.
Q: (L) Trace residuals in people. And there are supposed to be 36 million of them coming...
A: With the wave.
Kind of renders the term 'humanoid' obselete!
