The water is still on the earth, except for what water is in the clouds. The Holy Bible says the valleys sank and the mountains rose.
[b]The waters were standing above the mountains.
At Your rebuke they fled,
At the sound of Your thunder they hurried away.
The mountains rose; the valleys sank down
To the place which You established for them.
You set ...[text shortened]... ere not too many high mountains and the ocean and sea floors were not as deep.

The earth was relatively flat compared to the way it is today after the flood.
There is no geological evidence of Earth being much more flat just a few thousand years ago. In fact, the geological evidence clearly shows that the continents where about where they are now and the Earth was not more flat.
The earth split into the continents and water filled the gaps to make the oceans and seas.
This is known as continental drift and has been going on extremely slowly for many millions of years and there was oceans before that. The geological evidence shows that even back then many millions of years ago, when there was only one supercontinent, the earth was not more 'flat' in particular.
If the continents had split rapidly just a few thousand years ago over a distance of many thousands of km, this would have exposed the hot magma under the earth's crust that exists today and the oceanic crust, after it started to form, would not had time to cool down to a greater enough depth to form a crust that is a few km thick today plus the heat from the larva on such a vast scale being suddenly exposed to the entire floor of the ocean would have boiled the oceans which would have then super-heated the Earth’s atmosphere and killed all life. At the vary least, just like in Yellowstone park, if the floor was covered in larva just a few thousand years ago, we should expect to see in the present day active geological activity (in the form of hot-water vents in this case) on just about every square kilometre of the ocean floor area due to it still being in the process of cooling. But we don't see this so clearly this didn't happen.
