Before I get into the post proper I'd like to touch on this guy on Youtube calling himself the "Vigilant Christian." I recently listened to him talk about the church or the body of Christ. Near the end of this particular sermon the Vigilant Christian spent a few minutes talking about how Christians shouldn't criticize each other: instead of going around and attacking other Christians, a brother or sister should engaged in other (more constructive) efforts.
I immediately recognized what the VC (not Viet Cong) was doing. He was using manipulation. Not criticizing others is code for not pointing out false teaching (however subtle it may be) when you come across it. Constructive criticism is a good thing--when our motive is to help somebody improve. We are not to be busybodies--going around sticking our noses in other people's business; what we are called to do is to call out false or wrong teaching when we perceive it: that is everybody's business who is a part of the church. That's the ideal: that everybody in the church would have studied to show themselves approved--knowing how to rightly divide the word of truth. Sadly, that is far from the case in today's American church.
Now onto the post proper. We are told in Genesis 2:10: "And a river went out of Eden to water the garden..." To me, the way that is phrased, it sounds like the Garden was closed off from the rest of the land of Eden: the barrier may have been some sort of forcefield and so the Garden would have a nearly self-contained (except for that river from Eden) greenhouse-like environment; meanwhile the greater world had been engulfed in the last major ice age--known as "Wurm." The description of the lengendary Hyperborea says that it was a mountain island surrounded by turbulent seawater that made it inaccessible. Definitely a similarity there.
I think that the Garden of Eden or Hyperborea eventually became Sumeria, which was destroyed by Noah's flood (circa 5000 BC?). We are told in Jude that Enoch (son of Adam) was the seventh from Adam. However if we examine the genealogy in Genesis 5 we can only count six generations from Adam (the word "from" being important) to Enoch. Now if Jude decided to include an extra generation or descendant--whose name we are not given--then we can ask how many other descendants are not included. That's anybody's guess. It's plausible that quite a few generations have been skipped over, since the chronicler of Genesis was first and foremost concerned with showing a lineage from Adam to Noah (spanning just over 40,000 years)--whereby he is only interested in naming the prominent descendants: who, interestingly enough, are ten in number: there must be some significance in numerology involved. (All this I found on nabataea.net, along with what I say about Cain and the land of Nod below.) It may also be asserted that time prior to the flood was different. Before Adamic man--anything before about 50,000 BC--there may have been another kind of time. Miguel Goitizolo says that the previous interglacial period--between 180,000 BC to 150,000 BC--may have been when Lucifer reigned on the earth--implying that then was when his rebellion happened. (Personally, I believe this person called Lucifer goes back much further in time--millions of years. But then time was different then. And time is moving much faster now than it was long ago.)
Anyway, Cain was driven by God eastward into the land of Nod. Apparently Nod bordered on Eden. Cain founded a city he named after Enoch, his son. What has been discovered is that the letter "n" is frequently replaced with the letter "r." And the letters "ch" are often changed for the letter "k." Thus this city that was called "Enoch" was changed (in its spelling) to "Erech" or "Uruk." (My own version would be "Eruk," as in the 2nd drawing above.) After Noah's flood the post-diluvian city of Uruk was most likely established on the site of the prior Uruk.
Note how Uruk in the above map is more towards the east in comparison with the just about all the other cities. There's another Uruk just a bit to the northwest of Eridu. This other Uruk we can say with a good amount of certainty was not the Uruk or Enoch that Cain founded. By the way Eridu was where Adam established himself, once he and Eve had been driven from the Garden--which lay somewhere to the west. We can say that the children of Seth were in the west (Eden or later Sumeria) and Cain and his children lived in the adjacent area in the east called Nod.
After the local flood of Noah, the Ark came to settle somwhere along the eastern portion of the Ararat Mountains. It is from the east that the descendants of Noah--survivors of the flood--came to inhabit the post-flood Sumeria: witness Genesis 11:1-2 as it says that "the whole earth was of one language, and of one speech. And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar; and they dwelt there." At this time these people were under the rule of Nimrod (Sargon the Great), grandson of Ham.
Nimrod or Sargon's DNA was partly contributed to by the serpent back in the Garden. This came to be probably because Ham married Naamah a daughter of Cain. Then it would follow that this Sargon would have a prediliction for dominating others, as his father Sargon the Magnificent (Cain) would have had. Warfare between the Sethites and the Cainites may very well have been a reality.
Now moving further down the timeline (or more likely the time (sine) wave), we can see how Esau could and did sire children who had the serpent seed as part of their genetic makeup. We know that Esau took wives from among the daughters of Canaan, as Gen. 36 tells us. The land of Canaan was a land where the seed of the fallen angels (Nephilim) mixed with the serpent seed. (Most of the Canaanites were hybrids, it could be said.) We are told in Numbers 13:32-33 that ten out of the twelve men who spied out the land "brought up an evil report of the land which they had searched unto the children of Israel, saying, The land, through which we have gone to search it, is a land that eateth up the inhabitants thereof; and all the people that we saw in it are men of a great stature. And there we saw the giants, the sons of Anak, which come of the giants: and we were in our own sight as grasshoppers, and so we were in their sight." Caleb (and Joshua), on the other hand, had said, "Let us go up at once, and possess it; for we are well able to overcome it."
