Man, I'd love to see the full picture here but it's so muddied and few ever consider touching the topic, even those willing to stomach the truth.
What I can gather is that Cro Magnon is just a hybrid of native primitive man and "ancient aliens" and also beings (I've been going with "golems") they brought here to work on their behalf who they also inter-mated with.
Is there a difference between Man and Hu-Man?
It appears Neanderthal never died off, he lives in caves or generally underground and largely feeds off of the other monkeys while to some degree enacting control over them.
The parasites (noses; not Neanderthal) spent a long time snatching bodies or helping others ("reptilians") to as well as hunting Cro Magnon as well as leftover "ancient aliens".
From what I've gathered, the "ancient aliens" are what became gods of many societies, from Hindu gods to Greek gods, to Mesoamerican pale-skinned legends (again, gods). The spread all over the globe, seemingly after the most recent deluge.
