Like Coragyps, I also find it strange the Egyptians, Sumerians, the people of the Indus Valley Civilization, Chinese, and Australian Aborigenes, or for that matter any civilization, who have written and/or oral records dating from the time didn't seem to take notice of these runaway continents.
Given that the Egyptians relied on the annual flooding of the Nile for over three thousand years it would certainly take a miracle for the river to maintain both its course and behavior if entire continents were moving as such rates.
