The planet as a whole was caused to contract, a simple heart beat, if you will.
Thus, the water levels being constant, one can imagine how a contraction of the actual land mass would cause the entire orb to be covered in water, then when the land mass expands once more, voila, there are fish and horse skeletons everywhere.
neat, concise, covers all the facts...elegant.
Here’s the deal about theories. A)They have to explain all the available evidence, B)They have to be falsifiable (what evidence may be available that would disprove the theory?), and C)They have to provide a mechanism. Now, convince me...
Oh - and you’ve got to tell me where all that water went...
THE STATIC EARTH IS FACT!
Or, and just hear me out, or, we could use available evidence and use logic, reasoning and all available knowledge at our disposal. But creative writing can be fun also.
Sorry, but your theory sucks. If the earth was contracted enough for the sea level to rise above mountains the ensuing volcanic and tectonic activity would be enormous, likely enough to heat and make the oceans acidic enough to kill all life in them. Noah didn’t take any marine life with him so the question would have to be.... where did the vast variety of life in the oceans come from?
