That evidence can be explained also by other way, therefore it is not really evidence for what it is generally used.Again, evidence. We have it .
My claim was: Modern continents, mid-Atlantic ridge, orogenic mountains are evidence for that the flood came when the original single continent was broken and it's pieces sunk.Okay, you can show that I am wrong. What is your testable hypothesis that your evidence came from? What possible test could refute it?
To test could so happen, one could for example build a model of a single continent that has lot of water below it. That single continent would have "dust" on its surface, as the Bible tells and also lot of organic material. And the flood would begin with cracks forming in about the middle of the continent (like Mid-Atlantic Ridge). From those cracks water and water vapour would escape like from geyser. The escaping water would flood the dust towards the edges of the continent, causing sediment formations. The more water woudl escape belof the continent, the more the pieces of the continent would go down. While the pieces would go down, the sediments flushed to edges of the continent, would be compressed, which would then cause orogenic mountains.
That is one way to test, could the theory be true and explain such formations. If not, then it is possible that the theory is not true, or that the test was not done properly.
One thing that could explain it is the ice age and vast glaciers on top of very large areas. If there really was such glaciers, they could provide melting water many times in year, that could then carry stuff like nowadays different seasons do.By the way, you would have to show how many layers could be formed in a year and how that could have kept up for year after year.. If you can't you have nothing.
