that mountains bedrock are twice the size in depth to their height cannot be correct as mountains have different heights, and where there are no mountains there is still bedrock!
Hmmmm... sounds like taking a phrase in a holy book and trying to fit it to scientific discovery without really understanding the science and end up making the holy text look very silly indeed.

Sorry to be off topic but if people claim divine laws over Man's behaviour they had better have solid proof the 'Divine' exists. when science is used as proof they had better get it right ALL the time. Thus the rebuttal.
