yes the sumerians "came" later as a very gradual result of nodite intermarriage with the adamites to the north...they were concurrent. you will need to explain how the sumerians took over garden territory

the quote says north of sumer

Gradually, I would think, after the Second Garden.



Where is that quote (not doubting it exists, just wanting to see it in context)

What do make of this 'short way'? Appears to be another piece of circumstantial evidence against the northern theory. It must be explained since the northern pinch point was several hundred miles from the nearest point of the Euphrates to the First Garden.

76:1.3 (847.5) ...The two rivers themselves were a good natural defense in those days, and a short way north of the second garden the Euphrates and Tigris came close together so that a defense wall extending fifty-six miles could be built for the protection of the territory to the south and between the rivers.

Rick, have you considered that the paths the rivers flow in today are not the same as they were in antiquity?

Why not also take into account too what the Old Testament says about the second garden? The two unrecognized rivers that help identify the location are believed to have dried up long ago. Their likely locations have been reconstructed and several maps are viewable from the internet.

I agree that the upper triangle is a very interesting region that probably played a big role in Adamite/Andite cross fertilization with the rest of the world, even if it is not the location of the second garden.

It was fed by four tributaries which took origin in the coastal hills of the Edenic peninsula, and these are the “four heads” of the river which
“went out of Eden,” and which later became confused with the branches of the rivers surrounding the second garden.

The last three waves of Andites poured out of Mesopotamia between 8000
and 6000 B.C. these three great waves of culture were forced out of Mesopotamia by the pressure of the hill
tribes to the east and the harassment of the plainsmen of the west.

How wide and deep are the rivers near Cayonu, Turkey? Would they be a major obstacle to invaders? Do they run with much faster current? (becoming more dangerous to navigate)

I've always thought the land in Southern Mesopotamia would have been much too flat, hot and subject to major floods to stimulate and inspire the imagination of the Adamites...
