Carbon-14 decays to a zero amount in 250,000 supposed years after its production.It is incapable of yielding dates in the millions of years.If this water vapor did exist in the past, then it would have effectively shielded the atmosphere from much of the cosmic radiation.This shielding would have drastically reduced the amount of Carbon-14 produced.
In a similar way, solar cosmic radiation fluctuates and would cause a fluctuation in the amount Carbon-14 being produced at any one an ongoing process.
In nature, all systems are open regardless of what evolutionists say in protest. As no two people have exactly the same DNA, individual plants and animals vary in their physical and genetic makeup.
Even a sealed aquarium has sunlight, X-rays, Gamma Rays, ultra-violet light, etc. These variations cause individual organisms to absorb or reject Carbon-14 at different previously published radiocarbon dates must be corrected or mathematically weighted to correct the dates from the published dates to the actual dates.50,000 years it may be seen that the method is based on many false assumptions.
There is no instrument on earth that can detect Carbon-14 in a specimen that is supposedly older than 18 half-lives. There are, however, many false assumptions that must be made in order to derive Carbon-14 dates and the knowledge of these false assumptions demonstrates the uselessness in this other-wise supposedly useful not varied over the years. There is ample evidence to prove that quite the opposite is true.
Experiments done with the radioactive isotopes of Uranium-238 and Iron-57 have shown that rates not only do vary, but can, in fact, be altered by changing the environment surrounding the samples.
