Starting assumptions, as explained above, are always required to explain ancient, unrepeatable events. The hydroplate theory has one major and two minor starting assumptions. All else follows from them and the laws of physics. Proposed explanations for past events always have some initial conditions. Usually they are not mentioned.
Major Assumption: Subterranean Water. About half the water now in the oceans was once in interconnected chambers, 60 miles below the entire earth’s surface. At thousands of locations, the chamber’s sagging ceiling pressed against the chamber’s floor. These solid contacts will be called pillars. The average thickness of the subterranean water was at least 1 mile. Above the subterranean water was a granite crust; beneath that water was earth’s mantle. [See Figure 56.]
Minor Assumption 1: A Global Continent. The earth’s preflood crust encircled the globe. On the crust were deep and shallow seas, and mountains, generally smaller than those of today, but some perhaps 5,000 feet high.
Minor Assumption 2: An Initial Crack. A small initial crack occurred in the earth’s crust. (Several ways this crack could have started will soon be mentioned.) Once a deep crack formed, the high pressures in the chambers would have quickly propagated the crack around the earth.
All 25 major mysteries described earlier, such as major mountain ranges, ice ages, comets, and the Grand Canyon, are consequences of these assumptions. The chain of events that flows naturally from these starting conditions will now be described as an observer might relate those events. The events fall into four phases.
