Think about how much you trim off your fingernails each week. The Atlantic Ocean widens by about the same amount. Consider how long your nails would grow in two hundred and fifty million years. That is approximately how long it has been since Pangea broke up, giving us the Atlantic. Was that the only continental drift event? No. Godwana predates Pangea.
Our sense of time is pretty limited.
Regarding written accounts. Oral histories of North American, natives on the west coast seem to have documented the last ice age with stories of sea level fall and rise. Can you imagine the craft of passing down family and tribal histories through that many generations?
Food for thought.

You get it somewhat.
I just believe that fossil records record mass catastrophic events.
As do our legends and histories.
As does archeology.
The time span required could be much much less.
And what we know under the ice and oceans is very limited.
What G85 doesn't seem to grasp is the size of the scars the earth contains.
The surface floats, and a hit to the earth could initiate fairly rapid re-arrangement of the plates.
It would be far more violent than most of us are capable of imagining.
