That water beneath Asia is 1) chemically combined with the rock down there and not free to flow and 2) at a temperature somewhere over 1000F., and 3) spread very thinly through a enormous mass of rock. It won't help you much - you couldn't extract it with any speed, and if you could, you would also extract enough heat to sterilize the surface of the planet and hard-boil the Ark.
Nope.
"The Christian church, in its attitude toward science, shows the mind of a more or less enlightened man of the Thirteenth Century. It no longer believes that the earth is flat, but it is still convinced that prayer can cure after medicine fails." H L Mencken
