It was stated many years ago in answer to how did the flood cover the top of all the mountains on earth in Noah`s day.?
eg. Mount Everest ?
And it was explained away by saying that the mountains before the flood were a lot smaller / lower than the mountains that exist today.
So there was no problem .
When the deluge began with so much volume of water now covering the earth ( water being heavy ) pushed down into the weakest parts of the earth and raised up in other parts of the earth to where we now have higher mountains than existed before the flood of noah`s day.
In other words mount everest didn`t exist at its present height before the flood and neither did any other high mountain that exists today ,the topography all changed with the Noachian flood. .
According to JW /WT theology ,back then ,I wonder if they still subscribe to this reasoning. ?
Does anybody remember those days ?
