Plate tectonics is accepted by the vast majority of scientist since the evidence for it is overwhelming and not just in geology but in biology too. I won't waste either of our time trying to explain it you, I'm sure you've heard it all before.Your grasping at imaginary straws, Alang. Your suggestion is patently ridiculous as any geologist with an honest bone in his body would tell you. The fact is that the discovery was made and the evidence - even the discovery of marine sediment, fossils of corals and shellfish, at 2000 metres above sea level is rock solid proof that the flood happened.
You mention the discovery of marine sediments at the tops of mountains as evidence of a great flood. What you find, if you look at the layers of sediment in the Gulf of Mexico is much more complex. We've drilled through miles of sediments there and what we find is evidence of many, many individual floods, not just one. Every year the Mississippi would flood and leave a new layer of sediment and now there are tens of thousands of layers. If you looked at the Nile delta you find the same thing. The earth sure looks like it is very old.
