All clocks (including radiometric ones) require the use of at least three assumptions.
These are: In each of these cases it is not possible to prove that the assumptions are true.
As it decays, the helium not only accumulates in the rocks themselves, but also escapes from them and accumulates in the earth's atmosphere.
As time passes, the amount of helium in the atmosphere increases.
The shorter the time involved, the more likely that a specific process has been constant, and unaltered by external influences.
The following clocks point to a young earth, solar system, and universe.
This presents a problem for those who claim "millions of years" for the age of oil, simply because rocks are porous.
For as time goes by, the oil should seep into tiny pores in the surrounding rock, and, over time, reduce the pressure. Perhaps because our oil deposits were created as a result of Noah's Flood only about 4600 years ago?
Taken together, they suggest that the earth is quite young -- probably less than 10,000 years old.
The gravitational pull between the Earth and Moon causes the Earths oceans to have tides.
It is a complete mystery unless it was designed that way from the beginning.
When oil wells are drilled, the oil is almost always found to be under great pressure.
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.
