But God hath chosen the foolish things of the world to confound the wise;
and God hath chosen the weak things of the world to confound the things which are mighty;

"Earth’s iron-nickel core has a solid inner layer and a liquid outer layer. A recent paper presents a
Secular scientists had long assumed the inner core was initially in a liquid state but that lower temperatures caused the liquid at the center to begin to solidify. Supposedly the solid inner core grew over time, eventually reaching its presumed current diameter of about 760 miles.
However, the authors of this paper realized that this secular story had overlooked a critical detail: how the solidification process started in the first place. They realized this process required either
(1) a large, rapid temperature drop of about 1,000 degrees Celsius to a temperature below the core’s melting temperature, or
(2) the addition of an already-solid metallic nugget into the core.
--Since secular scientists think the core would require a billion years for its temperature to drop even one hundred degrees, they concluded that a rapid temperature drop was implausible. On the other hand, the metallic nugget would have started dissolving as it somehow dropped from the Earth’s mantle into the core. In order for this second scenario to work, the nugget would need to be ridiculously large, about 20 kilometers in diameter, for it to survive dissolution on its journey to the center of the Earth.
This means that secular scientists cannot, at present, plausibly account for the existence of the Earth’s inner core! So, if naturalistic processes cannot account for the existence of the inner core, then it appears to have been supernaturally created. This is what the Bible teaches and creation scientists strongly affirm.
There is an important lesson here. Creation scientists have long pointed out that the incredible complexity of living things demands a supernatural Creator. But this recent research shows just how difficult it is for secular scientists to explain the origin of even “simple” things, like Earth’s inner core. The structure of Earth’s core is trivially simple compared to the inner workings of a cell or the coded instructions in the DNA molecule. Hence, one would tend to think that these secular scientists would have no trouble at all explaining how Earth’s inner core formed. And yet they are at a complete loss to explain its origin." ICR
