OK so sounds right
But now let be fair and use the same math for a different test...The biblical flood..how much water needed. Where did it come from where did it go?
Flooding can can be temporary and localize..because flooded normal are top down.not bottom.up
Its been a while so I can’t give links etc but Biblical Flood came from great standing heavily moisture laden stratospheric somethingorother...also to explain great size of creatures and super-flourishing plant growth of Pre Flood Times.
This somethingorother let loose to drown the world. Of course God too gave us the rainbow as sign of a promise He would never so drown the world again.
