The Origin of Limestone

Too much limestone exists on Earth to have been formed, as evolutionists claim, by present processes on the Earth’s surface, such as the accumulation of pulverized corals and shells. Had that happened, so much carbon dioxide (CO2) would have been released that all of Earth’s surface waters and atmosphere would have become toxic hundreds of times over.

Before the flood, supercritical water in the subterranean chamber steadily dissolved certain minerals in the chamber’s floor and ceiling, making them increasingly porous and spongelike. This allowed even deeper dissolving. Rising temperatures in the chamber caused the limestone to precipitate (out-salt) onto the chamber floor. During the flood, the escaping subterranean water swept the precipitated limestone up to the Earth’s surface.
