The Earth's core appears to have a natural fission reactor (fueled by the decay of radioactive elements ), according to one theory. There would have to be a lot of uranium at the core for this to happen (or thorium and potassium.).
The sun is a natural fusion reactor. The heat and pressure in the core of the sun caused by the weight of all of that gas above it creates fusion of hydrogen to helium, releasing energy.

Believe what you believe, I respect that. But this is what the rest of us believe...
The incandecent ball of gas is not fueled like a fire. Nuclear reactions in the sun's core power the sun. The reaction, though continuous for the last 4.6 billion years, has not transformed enpough matter to energy that the sun loses too much mass. So it remains aproximately the same size.
The earth's core, on the other hand, is a solid lump of very hot iron. The heat cannot escape the inide because it is trapped by several layers of other stuff. Imagine the core is the middle of a freshly baked pie. Even if the surface of the pie is cool, the core is still hot enough to burn your tongue.
Beliefs are what make us human. :)

I think that what you don't understand has nothing at all to do with reality. if you had actually studied nuclear fusion, or astrophysics and thought these things, I'd be interested. But this is like me saying "I don't really thing Saudi Arabia exists b/c I've never been there. What do you guys think of this?"
The sun isn't "burning", it's fusing billions of tons of hydrogen and helium and other elements. It has a few billion years left and it will run out of lighter gases to fuse. The earth's core is hot from various source, nuclear radiation, friction, gravitational flexing etc...

The sun is a nuclear reactor in operation.
The Earth is heated by the sun and the core is slowing cooling down as the molten matter dissipates as volcanic eruptions and geysers. It takes a long (human) time, but in space time, a billion years is normal.

No "strange" power involved in either case. Radioactive decay heats Earth's core, and nuclear fusion powers the sun.

Well if you don’t believe sunlight is an incandescent reaction, then we really don't need to bother to explain anything. However the rest of us already know that the sun is heated by nuclear fusion, and that heat energizes the particles such that they glow (or incandesce).

the sun has has a small metallic core, it also uses hellium as it's fuel source
