The ratio of isotopes of the various elements varies from planet to planet. Recently an isotopic analysis of water found in rocks brought back from by astronauts on the Apollo 15 and 17 missions shows that water has the same deuterium- hydrogen ratios as is found on Earth and quite different. Deuterium is a heavy isotope hydrogen. This suggests that the water originate on Earth. However some of these rocks are would probably have resulted from magma from the Moons interior. This indicated that the water what resent when the Moon formed.
This result is fully consistent with Young Earth Creation model of the origin of planetary magnetic field developed by Dr, Russell Humphreys. Based on the reference to the deep on in Genesis 1:2 he concluded the the Earth had started out as a ball of water. The water was later used by God to start the Earth's Magnetic field.
Genesis 1:2 And the earth was without form, and void; and
darkness was upon the face of the deep. And the Spirit of
God moved upon the face of the waters.
Based on Genesis 1:6 and Psalm 148:4 he further proposed that when the water was divided the water above was pushed out in to space some of it being used to form the planets ant the Moon on day four of creation.
Genesis 1:6 And God said, Let there be a firmament in the
midst of the waters, and let it divide the waters from the waters.
Psalm 148:4 Praise him, ye heavens of heavens, and ye waters
that be above the heavens.
Being so close to the Earth it would be expected that he Moon's deuterium- hydrogen ratios would match those of the Earth. Thus we have here dramatic evidence in support of Humphreys' Young Earth model of planetary fields. A theory which has already had amazing success predicting planetary magnetic fields around the solar system including the observed decrease in Mercury's magnetic field.
