Have you ever studied about carbon dating? Do you that it's half life is only 5700 years...and that anything more than 50,000 years would be impossible to date using that method?
How accurate is Carbon-14 dating?
Did you know that 90% of the dating methods point to a young earth, not an old one? Why do you suppose evolutionists only cite the 10%? Because the 90% don't support their presuppositions.
In Australia, some wood found in Tertiary basalt was clearly buried in the lava flow that formed the basalt, as can be seen from the charring. The wood was "dated" by radiocarbon (14C) analysis at about 45,000 years old, but the basalt was "dated" by potassium-argon method at 45 million years old! How does 45,000 year old wood grow inside 45 million year old basalt...which, by the way, is known to have originated in a volcanic eruption about 150 years ago.
The Mount St Helen's (1980)lava flow was dated at somewhere between 25,000 and 2.5 million years old...depending on the dating method used.
Comment: there is some room for improvement in the methods, and there is "wiggle" room given the inconsistencies.
I am not familiar with the examples you cite. I just know that my Uncle helped drill wells in Saudi Arabia and used a myriad of geological dating methods that told him the Earth was much older than 8 thousand years old to find it. Sorry. But not only that. The scientific evidence is so overwhelming as to not even make me take you seriously any longer. You may as well say the Earth is flat.
Your name looks familiar enough that I suspect you should know better than to still be posting the kinds of statements you make here.
Radiometric Dating, a Christian Perspective, by Roger C. Wiens. All your recycled old chestnuts are dealt with there. Number 14 is your Mt. St. Helens story, which only shows that if some willful idiot wants to deliberately create a "bad" reading, he can. By the same logic, you can prove your old junk car is young by citing cases where somebody "fooled" an odometer. (By spinning his wheels on the ice or with the car up on blocks, for instance, or just tampering with the counter.)
