Granites and the foundations of the earth: Discovery of what God's Word has always plainly taught about their creation.
For centuries evolutionary geologists have told the world that granites originated from the cooling of a hot magma derived from sedimentary rocks. This is very similar to what you are now proposing, except they hypothesized slow cooling, and you want faster cooling. Believing themselves to be wise above that which was written for our admonition, upon whom the ends of the world have come, these geologists claimed to have sufficient expertise to interpret Earth's history, independent of the Bible anchor, and thus denigrated its abundantly clear declarations as to Earth's origin.
They scoffed at Psalm 33:6, 9 and its imperative declaration that the heavens and their entire host were called into existence by the breath of His mouth. Hence they scoffed at the existence of Genesis rocks, those called into existence at the beginning of creation week. Setting themselves up as geological authorities who had scientific truth, they ignored the many, clear biblical texts that show conclusively it is Earth's foundations rocks that are the Genesis rocks. Look at how many there are:
These repeated references to the foundations of the Earth focus attention on them as rocks that God created in the beginning, and interestingly enough, coincident with the heavens being the work of His hands. So we find that Earth's foundations are Earth's primordial rocks. That much is beyond doubt. And just what are these foundations?
