“Well then allow me to extrapolate a little more with this idea. The earth is 4.5 billion years old according to radio isotope dating - right?
—Yes, but not from any radiometric dating of earth rocks. No earth rocks have been found that are that old. The 4.5 million year date comes from date of the oldest meteorites and lunar samples. It’s possible that no earth rocks are left that are that old, they may have all weathered away or have been melted down since the formation of earth.
“But the rocks on the earth vary from millions, to hundreds of millions to a much as 3.5 billion - right? And these differently aged rocks all combined through accretion to make the earth - right?”
—No, there likely are no rocks left from the accretion stage. The “age” of a rock is the amount of time since it became, well, rock - from when it cooled from lava/magma. Rocks don’t just vary from millions to billions of years old, but from TODAY to billions of years old. There are rocks forming - right now. And rock is being melted down right now. So there’s a continual process of rock being melted down and being made. Because the earth is so geologically active, it’s to be expected that we’d find rocks of many different ages on earth - except for the very oldest rocks, where it’s best to look elsewhere.
Well then maybe you should discuss this w/ DevNet (see post 54) and get one or both of your stories corrected. And then explain all the age-dating anomolies found w/ the recent Mount St. Helens eruption.
Oooh - and please don’t forget to explain how all the layering that represents just one volcanic eruption differs from all other layering worldwide where each layer represents much longer time spans.
Is anyone else getting dizzy from all this circular logic?
