Lord Kelvin figured as much. Earth wasn't always liquid/solid material.
It's on the right hand side of the document, about half way down.
Gaseous to liquid state. All right!
H. H. Hess missed the point. I wrote a document overviewing this fact. He assumed Earth had little in the way of an atmosphere when it formed. The contrary is true. Now I have Lord Kelvin backing me up. Damn it feels good.
Not only that, but Lord Kelvin should have stretched it out a tad bit. Not only was the Earth gaseous, but it was fully ionized. We see these objects in the night sky. We call them stars.
