Abstract
Evolutionists believe that the Solar System is billions of years old. Even after all this alleged time, our own planet Earth still has not cooled. Its internal heat is evidenced by volcanic activity and the existence of a molten core. Electric currents circulate in this core, causing a magnetic field. This is already a problem for vast-age theories, and doubt exists about whether long-agers' appeal to radioactive heating is sufficient to keep the Earth from cooling down for more than a few hundred million years at the most.
