“These people that claim the earth is 13.7 billion years old know about as much about ...”
Actually, the Moon rocks collected on Apollo missions provide the best estimate of Earth’s age — 4.7 billion years.
Scientists tell us that the Moon and Earth were once one, and that some gigantic collision separated the original mass into two spheres.
The physical analysis of Moon rocks tell us that the composition of Earth and Moon rocks are similar, and - since little to no erosion happens on the Moon - that Moon rocks provide the best estimate for Earth’s age.
Radioactive dating tells us that rocks from the bottom of the Grand Canyon are not quite 2 bilion years old, and that Moon rocks are 4.7 billion years old.
Nothing is certain.
I know about Radioactive dating, I was a physical science major.
In Science, I witnessed more speculation than anything. All kinds of things claimed that couldn’t be quantified or seen.
Postulating this and postulating that. Postulating on a postulate.
Hypothesis grounded in more Hypothesis. Guesswork built on a foundation of guesswork.
Scientists these days have lost their way, I am afraid. They are driven to prove the agenda of their funding.
It’s actually been this way for awhile.
