I'm still not seeing anything that screams aliens. I guess I will have to read Zechariah Sitchin to find out where the rogue tenth planet that has to have its ozone layer fixed with gold mined from Earth comes from. With tens of thousands of Sumerian tablets recovered, it could be in there somewhere, but it's not in the stuff I've read.
The most interesting thing in the Epic of Gilgamesh is the encounter with "Noah," this time under the name "Utnapishtim" instead of "Atrahasis." There's a retelling of the flood myth which is the same as in the Atrahasis, but then we find out Enlil made Utnapishtim immortal after the flood. Gilgamesh finds Utnapishtim living in a deep underground base with the gods. This part does have science fiction like qualities, one can imagine it being done with technology. But then it could also just be a story.
One thing that strikes me about these stories is how casual encounters with the gods are. The same is true with Abram's encounter with God in Genesis, when they discuss the fate of Sodom and Gomorrah. It's as if they are men, and yet have a quality that makes them instantly recognizable as more than men. Encountering them isn't as shocking as meeting a Grey alien or something far beyond the ordinary. It could be explained if these are the elongated skull people, the Homo Capensis, and people aren't unused to seeing them yet. When they do see them though, they spot the conehead and know that these are the guys on top. Not saying this is for sure what happened, but it's a simple explanation. We know Homo Sapiens lived alongside a few other hominids, and we have elongated skulls that date back as recently as 900 years ago, so how crazy is it really?
If Homo Capensis is/was real, I can imagine they found themselves in a precarious situation when Homo Sapiens showed up. Given how sketchy it is to give birth to a baby with a head the size of Homo Sapiens, I'd guess giving birth to a Homo Capensis head is even riskier, and death in child birth more common. I'd guess that they had the disadvantage of reproducing more slowly than Homo Sapiens, but while they may have had an estimated average IQ of 150, and 15% were 180 or more, Homo Sapiens can also be that intelligent. It might not be as common among Homo Sapiens, but with more rapid population growth among Homo Sapiens, it is only a matter of time before there are more 150-180+ IQ individuals among Homo Sapiens than Homo Capensis. Most of the time that high of an IQ isn't even advantageous, it doesn't help anyone chuck a spear farther. But the smaller head and stouter neck of Homo Sapiens might. Sometimes being in the sweet spot is where its at. Homo Capensis may have figured out that the best way to deal with Homo Sapiens was to invent the priesthood. If Homo Capensis is an older race, their knowledge of astronomy would initially be beyond anything Homo Sapiens could imagine, and Homo Capensis could predict eclipses and such to establish themselves as miracle workers. Just a thought, may not be worth much at all. I think they'd have similar interests to the Annunaki though, the desire to keep the population size of Homo Sapiens in check. If the number of Homo Sapiens kept increasing, eventually there would be too many for Homo Capensis to rule. It's interesting how we see this theme pop up again in modern times with the Georgia Guidestones and concerns about overpopulation.
