I believe it was Charles Hapgood who proposed a theory along those lines. Like the skin of an orange sliding around the orange. That was why he said "Atlantis" was in Antarctica. It could make one think that such events would erase a lot of earth's history. There is a map, don't think it has been proven a fake yet, that shows the coastline of Antarctica even though it's under a bunch of ice. The Air force has taken some radar images which show the coastline, which aligns with the map.
For the "simple, there has to be more" folks like me, Graham Hancock"s "Fingerprints of the Gods" is a good read. He doesn't claim it as science.
