Is the interior of the earth hot?

From all I have seen from science the answer is we don't know. Obviously there is much heat below the surface in some areas, but that is basically close to the surface of the earth. (About maybe say a few hundred miles)
The reasons science thinks it is a hot core are all based on indirect evidence and more specifically a belief based interpreting of indirect evidence.
That would not be the only way a magnetic field could be produced. Nor are facts like some sound waves cannot pass through the core any reason to assume it is hot liquid! Nor is the lying cosmic evolution theories and stories any reason at all to think the core is hot. So...what's left? Any able to play the devil's advocate here and try to make a case that is must be hot?

 

Yet the fire consumes not. How hot is that?

 

It is not the kind of fire that physically burns away. So you cannot equate that to the inner core having to be hot. Jesus went down there to preach to spirits in prison there. He was fine, thank you very much.
