Then why do you find hydroplate and hydrologic sorting theories so attractive? The conditions you've imposed dictate that they can never be tested and the facts surrounding them can never be known.
We still haves loads of facts and data points - far more than any generation preceeding us - with possible exception to generations prior to Noah’s Flood [all of that accumulated knowledge was lost so mere conjecture now].
We can and should continue trying to conform our ideas and theories to all of the data points - the big picture - there is only one tried, trustworthy and true reality.
