Actually if you're trapped in that flood, yes it is. Then take into account it's worldwide. Then take into account that to keep the level going at 8cm a minute the rate of water has to continually increase as the sphere of water increases in volume. Very quickly that's a LOT of mass you've got moving all over the planet simultaneously for 40 days non-stop.<quoted text>
Have you ever experienced water rising around you at 8cm per minute? It's not very fast, is it?
Then double it if we cover Everest.
Not that we'd need to.
