The water is buoyant in itself, yes, it would float however the moment it leaves the seabed, air comes in to replace where the water has been. But, the air cannot support the water so it falls. Let us assume that your magical ocean has floated into the air. Let us theorise what would happen.
>Each water molecule is buoyant in water, so it can float.
>1.But, alas, the bottom layer of water molecules has no water below it, so has no buoyancy, so it falls.
>2.This exposes the next layer of water molecules, which have now lost the buoyancy of the lower layer. So, point 1. applies to it.
>3.This reasoning can be applied to every layer of water molecules, not only from the bottom but from the sides. So, the water would fall, layer by layer, back to earth.
So, your theory of floating oceans is flawed, because they could not stay afloat.
However, if this is too much for you to comprehend, it is provided in retard language below:
Arrgh! Uga uga! Big flying water! Big flying water floats in itself! But water at the bottom of big flying water fall down because there is not any water under big flying water. Big flying water not fly anymore, it just big water!
