Mt etna radiometric dating
Because helium is the second lightest element and a noble gas – meaning it does not combine with other atoms – it readily diffuses (leaks) out and eventually escapes into the atmosphere.
Helium diffuses so rapidly that all the helium should have leaked out in less than 100,000 years. While drilling deep Precambrian (pre-Flood) granite rocks in New Mexico, geologists extracted samples of zircon (zirconium silicate) crystals from different depths.
It is hard to see why this would be necessary if these were ‘absolute’ methods.
The entire geological ‘millions of years’ system was largely in place, based on the philosophical assumptions of men like Charles Lyell and James Hutton, before radioactivity was even discovered.
Very precise analysis from modern mass spectrometers can establish the date the living material in the sample stopped taking in carbon from the environment (the point of death).
Because C-14 has such a short half-life (radioactively decaying into Nitrogen 14), all detectable C-14 should have disappeared well before 100,000 years.
So far in this study we have learned that random natural processes cannot explain the emergence of life from non-living substances, or the advancement of species to more complex forms (such as ape-to-man evolution).
A major reason for supposing that such long ages of time preceded our present historical age has to do with the fact that such assumptions make it easier to explain the origin of the natural world in terms of (macro)evolution theory.If it did not create itself but was created by a Supernatural Being, then perhaps the natural world is younger than what we’ve always thought.In previous posts we’ve seen many instances of how the scientific world can make mistakes and hasn’t scored too well in understanding such obvious events as the Flood cataclysm and the resulting fossil record and geological re-construction of the Earth.Knowing how complex living organisms are – even a simple cell is anything but simple; it’s as complicated as a factory – then, for something like that to assemble itself by some natural (not supernatural) process, we can only think it would be incredibly difficult for that to happen.So if we ask how could anything so complex as the anything-but-simple cell ever come into being, and from there evolve into more complex structures by a process of unguided chance, this is the answer we would get.
The crystals contained not only uranium but also large amounts of helium.
