Well we can look at something more recent, and notice that the scientist in question, doesnt appear to be a biblical creationist, yet he is saying Britian seperated from from france due to a massive flood in only 24 hrs, he then goes on to say 200to 400,000 years ago.
After thinking of slow gradual erosion, they now believe a flood did it.

Its obvious that the bible tells this as a literal story,as history.
3 Know this first of all, that in the last days mockers will come with
their mocking, following after their own lusts,
4 and saying, "Where is the promise of His coming? For
ever since the fathers fell asleep, all continues just as it was from the beginning of creation."
5 For when[1]
[Or they are willfully ignorant of this fact, that ] they maintain this, it escapes their notice that by the word of God
the heavens existed long ago and
the earth was formed out of water and by water,
6 through which the world at that time was destroyed, being flooded with water.
7 But by His word the present heavens and earth are being reserved for fire, kept for the day of judgment and destruction of ungodly men.
37 "For the[25]
[Lit just as...were the days ] coming of the Son of Man will be just like the days of Noah.
38 "For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark,
39 and they did not understand[26]
[Lit know ] until the flood came and took them all away; so will the coming of the Son of Man be.
