I believe that is true, yes.
My own pet theory is that Neanderthal DNA is at least partially Nephilim DNA. Most people on earth have it, except for sub-saharan Africans, who are pure Homo Sapiens. The rest of Humanity are a hybrid species with 1-4 percent Neanderthal DNA, depending on individual and geographical location.
One thing to note is that Neanderthals had substantially larger brains than homo sapiens and some characteristics that allow Northern Eurasians to live in cold climates, such as a light skin tone, freckles, red hair and blue or green eyes are officially a remnant of Neanderthal characteristics. I think there is much to discover about the true history of Neanderthals and our co-existence with them until relatively recently. I very much doubt that they were the primitive brutes they are often depicted to be, the truth is very likely the opposite, given their much larger brains and sophisticated art, like the paintings in the Lascaux caves for instance.
