One question....er...maybe three?
Okay --- why have Venus and Mars obviously lost their magnetic fields long ago - probably longer ago than these recent guesses by geologists..? How old is the lunar soil? I thought this was already answered because of those three points. The Earth was completely reformed at the time period that is agreed on by geologists - however a giant collision reset the clock. The whole Earth Moon system was a giant blob of bubbling lava, the oceans just converted to steam like the atmosphere of Venus is now. If fact we would probably look just like Venus now, if some extraordinary realities were not present at that time.
If you change one factor just a little bit, it could be that water is the answer - maybe Earth had just that much more of it, and the collision was too slow to blow it all off, and so it enveloped the Earth Moon system in a black cloud until the lack of Sunlight froze the magma bubble into a sphere. Then by pure chaos, the water condensed from this frozen core and once again covered the earth - the moon however cooled too soon, even though it was every close to the Earth, and lost all its water by the Earth's gravitational pull, and the lack of a Van Allen belt. Its my theory and I'm sticking to it. The Bible arguments are so silly, when even a Christian knows they are just parables and nothing else - it wasn't necessary for God to explain himself, He is the Creator after all, He doesn't have to explain anything. I think I'll have a celebration tomorrow and have a pint to the Great One!
