Well Gary_Francis,
Mars has one hemisphere that has lost a lot of material, and although some attribute this to an explosion, I think it means Mars was in configuration with another planet. Thus we need to find another planet that has suffered material loss. If Earth's oceans were carved out electrically, and the edges and middle of the Atlantic show evidence for this, then an electric current flowing from one side of Mars to the north pole of Earth would account for it.
Now much material would flow with that current between Mars and Earth and so one would expect some of that material to found somewhere in the Solar System. The asteroid belt fits the bill well especially because it has mainly two types of rock in it.
Are there any ancient stories about something being at the north pole (maypole) or something being where the asteroid belt is now (Tiamat). What about the ancient extinctions ? Was one configuration responsible for these extinctions. Perhaps many planet conjunctions facilitated huge electric currents flowing between them. Then the new creatures came from another planet or were the result of plasma effects on DNA. Thus ony a few thousand years could account for the entire geological column.
But it is in the whole story that these various pieces of evidence gel together.
Cheers,
Mo
