There is 330,000,000 cubic miles of liquid water on the planet, which is most of what you see from outer space. Might as well call it planet water. Todays oceans are enormously deep. There is one basin in the Pacific that is 36,000 feet deep. Thats 6 miles down. If all the ice on earth melted, the oceans would rise 300 feet and all coastal cities in the world would vanish.
Where did all the water come from that caused the Noachian flood on planet mars?
And the conspiracy was strong, for the people increased continually - 2 Samuel 15:12
