sea, formed by rifting between the new Arabian plate and the African, which meant it had uplift ridges on both coasts. Many rivers and streams flowed from those ridges down into the Red Sea, but none of them carried much water compared to the rivers that drained vast basins and carried the melt-off of the glaciers of the north. So, while the Red Sea gradually rose during this time, it lagged far, far behind the great world ocean. Its water level responded to the immediate local weather patterns rather than to worldwide weather
Then one day the Indian Ocean rose so high that tides began to spill over the Bab al Mandab. The water cut new channels in the grassland there. Over a period of several years, the leakage grew, creating a series of large new tidal lakes on the Hanish Plain. And then one day, some fourteen thousand years ago, the flow cut a channel so deep that it didn't dry up at low tide, and the water kept flowing, cutting the channel deeper and deeper, until those tidal lakes were full, and brimmed over. With the weight of the Indian Ocean behind it the water gushed into the basin of the Red Sea in a vast flood that in a few days brought the Red Sea up to the level of the world ocean
This isn't just the boundary marker between useful and useless water level data, thought Kemal. This is a cataclysm, one of the rare times when a single event changes vast reaches of land in a period of time short enough that human beings could notice it. And, for once, this cataclysm happened in an era when human beings were there. It was not only possible but likely that someone saw this flood--indeed, that it killed many, for the southern end of the Red Sea basin was rich savannah and marshes up to the moment when the ocean broke through, and surely the humans of fourteen thousand years ago would have hunted there. Would have gathered seeds and fruits and berries there. Some hunting party must have seen, from the peaks of the Dehalak mountains, the great walls of water that roared up the plain, breaking and parting around the slopes of the Dehalaks, making islands of them
Such a hunting party would have known that their families had been killed by this water. What would they have thought? Surely that some god was angry with them. That the world had been done away, buried under the sea. And if they survived, if they found a way to the Eritrean shore after the great turbulent waves settled down to the more placid waters of the new, deeper sea, they would tell the tale to anyone who would listen. And for a few years they could take their hearers to the water's edge, show them the treetops barely rising above the surface of the sea, and tell them tales of all that had been buried under the waves
Noah, thought Kemal. Gilgamesh. Atlantis. The stories were believed
The stories were remembered. Of course they forgot where it happened--the civilizations that learned to write their stories naturally transposed the events to locations that they knew. But they remembered the things that mattered. What did the flood story of Noah say? Not just rain, no, it wasn't a flood caused by rain alone. The "fountains of the great deep" broke open. No local flood on the Mesopotamian plain would cause that image to be part of the story. But the great wall of water from the Indian Ocean, coming on the heels of years of steadily increasing rain--THAT would bring those words to the storytellers' lips, generation after generation, for ten thousand years until they could be written down
As for Atlantis, everyone was so sure they had found it years ago
Santorini--Thios--the Aegean island that blew up. But the oldest stories of Atlantis said nothing of blowing up in a volcano. They spoke only of the great civilization sinking into the sea. The supposition was that later visitors came to Santorini and, seeing water where an island city used to be, assumed that it had sunk, knowing nothing of the volcanic eruption. To Kemal, however, this now seemed far-fetched indeed, compared to the way it would have looked to the people of Atlantis themselves, somewhere on the Mits'iwa Plain, when the Red Sea seemed to leap up in its bed, engulfing the city. THAT would be sinking into the sea! No explosion, just water.
