Doctor Isaac Thermal Energy From Radioactive Processes Is a Major Source of Heat in the Earth

Thermal energy from radioactive processes is a major source of heat in the earth. If those processes were accelerated by many orders of magnitude, the earth would have quickly evaporated from the heat. So why didn't the oceans freeze? Why didn't noah's family and all the animals turn into corpse sickles s due to the super cooling factor that was keeping earth's crust from melting? Would there be ways around these problems? Again, an omnipotent god can do whatever he chooses. But at that point we're piling on the miracles.
