Dating zircon crystals
All of the proposed theories as to where it came from have serious problems.It is a complete mystery unless it was designed that way from the beginning.Or to say it another way: there is a LOT of scientific evidence that suggests the Earth is perhaps only thousands of years old, and that the year age that evolution-believing "scientists" have LOUDLY and repeatedly proclaimed to be a fact, is actually based on a strong desire to eliminate God from His own Creation rather than on scientific facts.A "clock" is any geophysical or astronomical process that is changing at a constant rate.From this they estimate the amount of helium that should be produced, and from these they can calculate how much helium is being added to the atmosphere over a given amount of time.
Kent Hovind noticed the same thing and explains why in ahe gave at U. In this regard Francis Crick, one of the discoverers of DNA's structure, proposed that life must have come from Contrary to what we've been told over and over by the mass media, the "scientific" establishment, and old-Earth (slow) Creationists, there are numerous geophysical and astronomical clocks which point to a young age for the earth, solar system, and universe.
Helium is a byproduct of the radioactive decay of uranium-238 as it decays into various different elements into its final stable element: lead 206.
As it decays, the helium not only accumulates in the rocks themselves, but also escapes from them and accumulates in the earth's atmosphere.
It also strongly suggests that something happened around 4,500 to Note also that it is possible for trees to produce more than one growth ring per year, which would shorten the above estimated ages of these trees.
Also, with regard to fossil tree rings, the author has been unable to find any documented instances of fossil trees having more than about 1500 rings.
