Just two very minor points......
Fossils are created individually at any time, and the amount of time depends on where they are, but it does need enough deposits to make enough weight to turn it into stone. Where would Billions of tons of deposits come from in one go, considering Noah's flood came from rain that would not shift enough debri.
But more importantly, their just is not enough water on this planet to do what it says in the Bible, only enough to flood, if all the ice meltded sea level would rise no more than 300ft, I'd still have to drive miles to get to the beach

.....but at least Manchester will be gone

.....and Liverpool

We'd still have Tranmere though
