Glaciers move. They move forward (procession) and backward (recession). When they move forward a mass of rock and rubble is pushed ahead of the glacier which is called a moraine. When a glacier regresses, the moraine is left behind as a ridge of unconsolidated rocks from the face of the glacier and curving around the tongue. The last Ice Age ended not all at once but with a sequence of starts and stops of glacial regression and progression. The progressions were not however as massive as the regressions. This left a series of glacial moraines as seen in the following photograph; If the Ice Age ended in the creationist fantasy described in the OP, there would be no regression sets of moraines such as are found all around the world. Further, we have ice cores which show many thousands of layers formed by the annual accumulation of snow that then melts and refreezes as ice. This is how a glacier grows. Each ice layer also accumulates a years worth of dust, and this is often dust produced by volcanic eruptions. These dust layers stay discrete and this way we know that they are deposited sequentially and not all at once. You can see some massive dust deposits clearly in the top photo and in the one below; What would have happened to the ice in these layers during a global flood? Ice floats, and minimally the glaciers of the world would have all broken into ice bergs. There would be no retreat moraines, and no layered ice sheets.

Some of the evidence presented at the Acapulco meeting of American Geophysical Union for the comet theory.

Don't know if the timing would have been right for the hypothetical Black Sea flooding. I'm pretty doubtful that an event of this size would have had that drastic an effect that far away. On the other hand the breakdown of the ice dams in Canada and the Northern US which led to the catastrophic drainage of the major glacial lakes they held back caused some pretty spectacular local phenomena like the "scablands" in Washington State and Oregon. |

I compiled this from various IIDB posters - a total demolition of the flood myth from just about every angle

Well into the twentieth century, dwellers in the Tigris-Euphrates delta would deal with seasonal floods by moving bag, baggage, and livestock onto rafts made of reeds.
It is almost certain that, unable to farm, they passed the time fishing and telling tall stories about great floods of the past. Tall tales inevitably get taller over time. (Grandpa likes to impress the kiddies.) This is all reasonable. What is unreasonable is that thousands of years later, supposedly adult people are so credulous as to believe these Munchausenisms. |
