Now, I'm going to assume that was true. How, outside of magic, did the iron core of the planet get there and how did the mantle become molten if during the creation of the planet, Earth wasn't molten at all, but "void and empty?"
The topic title question:
Where did Earth's Iron core come from and how did the mantle become molten?
For all the blather that has happened, NOBODY has done much of anything to answer the topic title question.
So, obvious Child, what is your answer to the topic title question? At least a basic outline of such probably should have been in message 1.
