By far, I mean in time and space. This is no lecture, I'm simply posing the question as I wish to know.

The flood starting around 5600 bce, is it possible that it affected a land as far as Dilmun (a federation of sorts, with it's center in modern day Bahrain in Persian Gulf) and over 2,000 years later?

Around 3,000 bce the land of Dilmun (already inhabited for 7,000 years approximately, and agriculturely advanced since 5,000bce) started to see their first civilization attempts. The same time as (supposedly) the great Gilgamesh traversed the region to Dilmun for it's fountain of youth/everlasting life source.

Now, Dilmun was known as a virtual paradise at the time, but we don't know how long before that it was considered such a land of camelmilk and honey. As civilization built up, a city center with a fortified base was created.

Those photos are of a local excavation site called Saar Archeological project. The city itself dates to around 3,000 bce. But the flood was much earlier obviously. So, my question again is, is it possible that as much as 2500-3000 years later the land of Dilmun was still being affected by it?

I think in some aspects, yes it may have been, and more importantly, that some of the peoples migrating away from flooded areas and coming to settle on more southern climbs may have heard discovery of Dilmun (through Dilmun's great trade routes, which is how it came to be such a paradise of wealth then) and eventually wove it into their tales as a sort of Shangri-la.. a land of paradise, where animal husbandry was easier, plants grew in abundance and the source of life came from. Eventually making that trek themselves, until Dilmun grew out of few inhabitants to a virtual foundation. Of course, it was later overcome by the Mesopotamian empire, and at an earlier point by Indus Valley civilization.

A point to consider in opposition is in local legend and in nearly all regional myths (including Persian), Dilmun is the 'Garden of Eden'. I have found no scientific research to back that up, and seeing as how it was only inhabited since 10,000 bce and lunar cycle + Goddess worshipping culture ever since until late Persian rule, it being the real garden of eden (if there is such a thing, I'm not getting into that here) would be highly unlikely. But we need to remember that in local culture, most myths and tales come from no earlier than 5,000 bce. With myth being of similar time frame, why would people say that they all originated from Dilmun and not how they managed to get to it? Seems to me that they would tell stories of how their people migrated, and all the trials and tribulations they experienced along the way... at least that's what I would weave into my stories for my children/grandchildren.

Perhaps they removed themselves from their history and their migration to avoid regional disputes carried over from the pre-flood plains?

I am unsure, but will welcome anyone's feedback or additional input on this to formulate my own opinion one way or another. When in gram conversation I asked Apiladey about this, he gave me this very interesting tidbit in reply... of which I'm now very interested in finding out more about it! :

"You know, there was another theory about the flood story in Mesopotamia. It was connected to a dam of silt being deposited at the mouth of the rivers. There was some geological evidence for it, causing waters to back up greatly in the area. That one would have held lots of importance to Dilmum."

Obviously, there are no references to list as this post contained no research, just some ideas. However, if you wish to find out more about any of these topics I have some great links and I know Apil has some great book references on the all the topics covered as well. Just ask!
