Naturalists deny any possibility of a global flood here on Earth, yet they've begun talking about the very same on Mars. In fact, they believe there are great glaciers of frozen water underneath the surfaces of Mars, Titan (moon of Saturn), Ganymede, Callisto, and Europa (these last three are moons of Jupiter). For Mars in particular, Naturalists are now suggesting its global flood may have happened "when large amounts of groundwater burst on to the surface" of the planet, a la "fountains of the deep" (Proverbs 8:28).
[S]ecular researchers have no problem accepting a global or near-global flood or floods on Mars, despite not having found a drop of liquid water anywhere on Mars to date (and even before there was any ice found). But a global Flood on Earth, a planet that is mostly covered by water? No way! How could that be? "Where is all the water for such a flood?", they mockingly ask, seemingly oblivious to the fact that they are standing on a planet that is mostly covered by water.
Note that Earth is mostly covered by liquid water, something that hasn't been found to exist elsewhere in our Solar system. Elsewhere, any water found is locked up in its frozen form, although the gas giants may have some water vapor at particular altitudes of their atmospheres. [The term "ice", as used by astronomers, can mean other frozen substances and not just frozen water. "Water", on the other hand, is H2O in most any of its forms, frozen, liquid, or vapor.]
"Fountains of the great deep" are not a problem, it seems—anywhere but on Earth which is two-thirds covered with water. In fact, there is so much water in Earth’s oceans alone that if its surface features were smoothed out, the water would cover the planet to a depth of about 3 km (1.8 miles). Furthermore, seismic studies suggest that beneath the surface, in one form or another, there is still sufficient water to fill Earth’s oceans more than ten times over again.
Notice how stupid one can be when one's worldview is in gross error.
