(1) I am on topic.
(2) I wanna know everything you said about me on another forum.
(3) I just thought I threw this one out there since both you and I know the "you can't know for sure since no one has been there" argument is bound to show up in a topic like this.

Even if we remove the issue of the iron core, how did a dead empty rock ball turn molten under the crust?
As Archangel already pointed out, the Earth was just a hunk of rock floating through nothingness long before G-D breathed life upon it. This would explain the apparent old age of the Earth.
But more importantly, we should look at other angles. The Sun, Moon, and other planets were placed around Earth. Their gravitational influences, over time, began to have adverse effects on the Earth's geology. Anyone with the most basic knowledge in physics knows that gravitational bodies exert gravitational tidal waves on each other. But just in case we have people that don't know what I'm talking about, let me briefly explain.
When we have two massive bodies in close range with each other, they attract each other based on the inverse squared law. Distance being the key in the equation. Say we have objects A and B. The side of object A that faces object B is obviously a lot closer to object B than the side of object A that faces away from object B. The gravitational influence of object B on the far side of object A is considerably less than the gravitational influence of object B on the near side of object A. Therefore, we end up with what we call the tidal wave effect. Object A's shape is slightly altered to more like a pumpkin shape as one side is pulled toward object B with a stronger gravitational magnitude than the other side.
This is why we have tides on Earth and Enceladus is considerably warmer than what it should be that far out.
Going back to Earth, after G-D put the planetary bodies around Earth, their gravitational effects started to work on the Earth. The Earth began to be geologically active. One of these effects is the heat generated by friction as one side of the Earth is pulled toward the Moon a lot stronger than the other side.
Try to beat that explanation!
