I read somewhere it goes back to the Annunaki Nephillim stuff. Back then everyone was brown and brown hair and they came along white with blonde hair. Or they actually had gold skin? If they were aliens and got here thats certainly possible considering all the talk about gold in our DNA recently.
Also a bunch of the Pharoahs were said to be descended from the Nephilim, and have already been proven to have blonde hair from the mummies. And Queen Scota and all them Phaaroahs and Queens are supposedly part of the modern Royal bloodlines and they all do the incest thing to preserve their hybrid nephilim alien dna. So all the talk about bloodlines is people who either are or aren't but seriously think they are part alien and therefore royalty and therefore cooler than you and therefore can make your life a shitty hell while they sit around and wait for the mothership to come and suck them back up into some quantum land of talking white bunny rabbits n gold nuggets for breakfast.
