Some large body came by earth way back when and pulled the material out into space where it recollected forming the moon.

Since the iron core model of the earth doesn't work for me (because of the jaggedly wandering poles), I have my thoughts on the movement of continents and the Pacific Basin also. The nature of our magnetic field with it's flips, etc., resembles more a nuclear core than just an iron core. If only 1 percent of the magnetic strength is able to get through the mantle of the earth, then there may be some other physics going on. Perhaps a Meissner effect that could have spread the continents apart.

(Just a word to the scientifically wise because this has implications that I don't want to get into publically...and that's all I have to say about that...:^)...)

One way to find out what's down there. Core sample. A REAL Core sample from the Core. I am still entertaining the possibility that the atmosphere of earth is responsible for the earth's magnetic field. Earth's core may be iron, but it needn't be magnetized, and even though rotating needn't generate a mag field by any means including cutting flux lines emanating from the sun or Jupiter.
