This is the most objective, scientific, up to date information about the elongated skulls that share Caucasian DNA and have RED hair.
These skulls are apparently found in many places and it's probable to theorize these beings pro-generated the Caucasian "race" (Think of it as an array of ethnicities by this point)
Some people think they are martian and left Mars due to geological cataclysms/war, etc. Some say Nibiru. Whatever they are they seem "alien" and are just a bit removed from what we now think of as a normal human physiology.
These "long-skulled" individuals no doubt are the beings who in legend and myth would have "begat giants" and been capable of genetic alterations.
Let's suppose though, that these beings had a global civilization that was eradicated, and then they gathered predominately in Atlantis which also eventually had an additional cataclysm.
These survivors of Atlantis = The Phoenicians.
It's worth noting that many of these Atlantean survivors aren't necessarily bad people, just CERTAIN CLANS or let's say "Societies"
I also theorize that Enki, Enlil, Anu…etc…Survivors of Atlantis.
In the post-apocalypse era their technology made them into gods via gradual mythologizing.
