Scientists cannot account for the amount of He3 in the atmosphere. To be stable and have reasonable living conditions, only 2ft of water could be held in the WV canopy. Creationists are working on these. Numerous invertebrates appear suddenly in rock strata above Pre-Cambrian devoid of complex fossils. Creation of Sun, Moon, stars, etc.
Planets have widely different compositions.
Depth on Moon's surface gives an age in the order of only 10,000 yrs. The dust contains a percentage of Nickel, but tests show less than 10,000 years' worth of Nickel in the oceans. Having said this, measurement of the amount is very difficult and a recent investigation indicates that it is much less than the early measurements. From this, the young age of the earth cannot be proven with this much smaller annual amount. This process should have swept the dust from the planetary system within 2.5 million years - yet it is still there, indicating that the age of the earth is less than this value.
