Just to add, at this point I am not trying to fit what I am saying into the biblical 6000 years. I’m just trying to see if the "Perfect Earth" is attainable.
Wasn't the starting point here to try and fit this into a biblical frame though? If not we are going severely off topic here.
-But as I alluded to in the previous post, I don't see the point of seeing if this idea is attainable, because even if earth was structurally perfect at one point in time because the ocean waters were out in space as your hypothesis says, this must have been long before mankind came on the scene, and must also have ended (the water must have come down) long before mankind came on the scene.
We know this because of radiometric dating methods, but also because we can use GPS measurements to see exactly at what rate the continents drift apart. And if they have drifted apart at a steady rate, that in itself shows their separation must have taken very very long (to say the least). If the continents haven't drifted apart at a steady rate, but we are to suppose that they were 'collected' ~4000 years ago to allow for a structurally perfect crust back then (before the flood), they must have had an incredible speed at first and later slowed down to a screeching halt (I haven't done the math, but that kind of speed couldn't be good for the life on those continents).
Another thing is that if the waters that now form the oceans of the planet were suspended in space back then, was it God's plan then to never let that water fall on earth if mankind had remained loyal? Would we then never have had mountain ranges and oceans like we do now? Would we never have seen the sun or the stars?
Another thing (#2), is that I believe such a mass of solid water out there (actually it would have to be ice because of the temperature in space) surrounding earth would be mechanically unstable and either disintegrate or crash into us.
Another thing (#3) is that the way earth is formed, it has a molten, very hot interior, with various 'layers' throughout, and these rotate and grind on each other as the earth rotates. I can't be sure, but I suspect that even without the current fault lines and plates and oceanic pressure, there would be breakage of the stiff crust caused by this movement and its resulting 'ripples' over the surface. So some kind of lava/magma flow to the surface would probably still have occurred, and some breakage leading to quakes as well, although perhaps not as much as today. But as far as I know, plate tectonics do not rely on the pressure of the oceans to account for the movement of the plates. So I'm not so sure it would even make a difference if the waters were not present.
I am curious though; does God play a role in your 'hypothesis' at all, or are you trying to find natural causes for what later became myths?
